1. Hedman Hedders 69090: Best Overall for Street/Strip
In our evaluation, the Hedman Hedders 69090 emerged as the top all-around performer. Based on manufacturer specs and owner feedback, these full-length headers provide substantial gains in horsepower and torque across the powerband. The 1 5/8-inch primary tubes are ideal for mild to moderately built 350s. The 14-gauge flanges are thicker than many competitors, reducing the risk of leaks. However, the standard black paint may discolor or peel after extended high-heat use; upgrading to ceramic coating is recommended for longevity.
These headers are a solid choice for street-driven trucks and muscle cars where fitment is straightforward. However, they may not be ideal for extreme lowered vehicles or those with tight steering shaft clearance. Owners of heavily modified 350s with large displacement may prefer larger primary tubes. For most builders, though, the Hedman 69090 offers the best balance of performance and value.
- Proven power gains across the RPM range, especially mid-range torque.
- Thick 14-gauge flanges resist warping; ceramic coating option available.
- Direct fit for most Chevy 350 applications including trucks and muscle cars.
Pros: Excellent build quality and gasket sealing.; Noticeable throttle response improvement in owner reports.
Cons: Paint can burn off over time without ceramic coating.
2. Flowtech 31140FLT: Best Budget Pick
For those on a tight budget, the Flowtech 31140FLT delivers solid performance without breaking the bank. We compared its spec sheet against more expensive headers and found it offers similar primary tube sizing and collector design. Owner feedback indicates noticeable gains over stock manifolds, especially in the mid-range. The silver paint holds up reasonably well, though it is not as durable as ceramic coatings. The included gaskets and hardware simplify installation.
The main compromise is the thinner flange material, which requires careful torquing to avoid leaks. Some owners reported warping after several heat cycles if bolts were not retorqued. This header is best for weekend projects or vehicles that see occasional street use. For daily drivers or high-heat applications, investing in a header with thicker flanges is advisable.
- Affordable entry into full-length headers without sacrificing basic performance.
- Fits most Chevy 350 applications with standard port spacing.
- Includes gaskets and hardware for a complete install.
Pros: Very cost-effective solution for budget builds.; Simple bolt-on installation with no modifications required.
Cons: Thinner flanges (5/16 in.) may warp if over-torqued.
3. Doug's Headers D333: Premium Full-Length Choice
When we evaluated the Doug’s Headers D333, the attention to detail stood out. The 304 stainless steel construction offers outstanding durability and a polished appearance that lasts. Based on manufacturer data, these headers flow exceptionally well, contributing to peak horsepower gains of up to 20 hp on a mild 350. The CNC-machined flanges are flat and thick, virtually eliminating leak issues. Owner feedback consistently praises the fit and finish.
These headers are a premium investment and best suited for enthusiasts who want a set-and-forget solution. The stainless steel will not rust, making them ideal for trucks exposed to road salt or moisture. However, the cost may be prohibitive for budget builders. If you are building a high-end street machine or a show truck, the Doug’s D333 is a top contender.
- Premium 304 stainless steel construction resists corrosion and heat discoloration.
- CNC-machined flanges ensure a perfect seal every time.
- Designed for maximum flow with mandrel-bent tubes and smooth transitions.
Pros: Exceptional build quality and longevity.; No need for ceramic coating; stainless looks great.
Cons: Higher price point may not suit all budgets.
4. JBA Performance Headers 1675S: Best Shorty Headers for Trucks
For truck owners who want improved exhaust flow without sacrificing ground clearance or dealing with complex installation, the JBA Performance Headers 1675S shorty headers are an excellent choice. We researched owner feedback from truck forums and found consistent praise for the hassle-free fitment. The stainless steel build ensures long life, and the shorty design works well with stock or aftermarket exhaust systems. Performance gains are modest but noticeable, especially in the low-to-mid RPM range.
These headers are not intended for maximum horsepower builds. If you are chasing every last pony on a drag strip, full-length headers will outperform. However, for daily-driven trucks, tow rigs, or lifted 4x4s where clearance matters, the JBA 1675S is a reliable upgrade. The only downside is that they may not clear some aftermarket starter motors; check fitment before purchase.
- Shorty design simplifies installation and retains ground clearance.
- Stainless steel construction with polished finish.
- Direct fit for Chevy 350 trucks with OEM-style port configuration.
Pros: Easy bolt-on with no clearance issues.; Good for trucks with limited space (e.g., 4×4, lowered).
Cons: Less peak power gain compared to full-length headers.
5. Hooker Headers 2451HKR: Best for Performance Trucks
Hooker is a well-known name in performance headers, and the 2451HKR model lives up to the reputation. In our analysis, these headers are ideal for Chevy 350s with performance camshafts, aftermarket cylinder heads, or forced induction. The 1 3/4-inch primary tubes allow for excellent top-end power. The ceramic coating is a practical upgrade that helps keep engine bay temperatures down and protects against rust. Owner reports highlight significant power gains on dyno-tested builds.
Installation can be more challenging than shorty headers, especially on trucks with limited space. Some owners reported needing to dimple the primary tubes for steering shaft clearance on certain models. These headers are best for experienced builders or those willing to do minor adjustments. For a mild street 350, the 1 5/8-inch primaries of other options may be a better match.
- Larger 1 3/4 in. primaries for high-horsepower 350 builds.
- Ceramic coating reduces underhood temperatures and resists corrosion.
- Proven performance in truck and muscle car applications.
Pros: Designed for high-flow applications; supports 400+ hp.; Ceramic coating improves durability and heat management.
Cons: Tighter fitment may require modifications for some trucks.
6. Speed Engineering 350 Header Set: Best Stainless Value
Speed Engineering offers a stainless steel header set that appeals to those wanting corrosion resistance without the premium price of Doug’s or JBA. Based on our research, the primary tube sizing and collector design are standard, and owner feedback indicates power gains similar to other budget headers. The mandrel bends help maintain exhaust velocity. However, we found mixed reviews regarding fitment. Some owners on truck forums noted that the headers required grinding or denting to clear the frame or steering components.
These headers are a gamble on fitment but can be a great value if they work with your specific vehicle. They are best for hobbyists who are comfortable with modifications. If you want a guaranteed bolt-in experience, consider spending more on a brand with a stronger fitment reputation. For a weekend project with a standard Chevy 350 in a classic truck, these may work well.
- Affordable stainless steel full-length headers for budget-minded builders.
- Mandrel-bent tubes for smooth flow.
- Includes gaskets and bolts for installation.
Pros: Stainless steel at a competitive price point.; Decent performance gains for the cost.
Cons: Inconsistent fitment; some owners report clearance issues.
7. Pacesetter 70-1125: Budget Mid-Length Option
The Pacesetter 70-1125 is a budget-friendly mid-length header that fits a wide range of Chevy 350 vehicles. In our evaluation, the mid-length design provides a modest performance improvement over stock manifolds, though not as much as full-length headers. The 2.5-inch collector is smaller than typical 3-inch units, which can limit top-end power. Owner feedback frequently mentions that the black paint burns off within months, leading to surface rust. The flanges are adequate but not as robust as premium brands.
This header is suitable for a low-budget project where cost is the primary concern. It will work for a daily driver or mild street truck, but expect to repaint or replace them sooner than higher-end options. If you plan to keep the vehicle long-term or want reliable performance, we recommend saving for a better-built header. For a quick, cheap upgrade, the Pacesetter gets the job done.
- Mid-length design offers a compromise between shorty and full-length.
- Affordable price point for entry-level upgrades.
- Direct fit for many Chevy 350 applications.
Pros: Lower cost makes it accessible for budget builds.; Slightly easier installation than full-length headers.
Cons: Paint durability is poor; may peel quickly.
Frequently Asked Questions
What size headers should I choose for my Chevy 350?
For most mild street 350s (up to 350 hp), 1 5/8-inch primary tubes are ideal. For higher horsepower builds (400+ hp), 1 3/4-inch primaries help top-end flow. Collector size is typically 3 inches for full-length headers. Always match the header size to your engine’s output and intended use.
Are shorty headers better than full-length for trucks?
Shorty headers are easier to install, maintain ground clearance, and fit tight engine bays. However, full-length headers generally produce more peak horsepower and torque. For lifted trucks or towing, full-length may be better if clearance permits. For lowered or 4×4 trucks, shorty headers are often the practical choice.
Do I need ceramic-coated headers?
Ceramic coating reduces underhood temperatures, resists corrosion, and extends header life. It is not strictly necessary but recommended for daily drivers or vehicles in humid/salty environments. Painted headers can work but may rust or discolor over time.
Will headers fit my Chevy 350 truck without modification?
Most headers are designed as direct fit for specific applications, but some require minor adjustments like dimpling tubes for steering shaft clearance or trimming bolts. Check manufacturer fitment notes and owner forums for your exact truck model before purchasing.
Can I install headers myself?
Yes, many enthusiasts install headers at home with basic hand tools. However, access to bolts can be tight, and you may need to lift the engine or remove components. If you are not comfortable with mechanical work, professional installation is recommended.
