1. AFR 195cc Eliminator: Best Overall
The AFR 195cc Eliminator heads deliver exceptional airflow and power potential right out of the box. In our research, they consistently show flow numbers that rival larger port heads, making them a top choice for street/strip engines up to 450 horsepower. Owners report easy installation with standard valvetrain components and minimal tuning required. The 64cc chamber works well with flat-top pistons for a compression ratio around 10.5:1 on a 350.
However, these heads carry a significant investment. For budget-conscious builders or those targeting modest power gains, the cost may be hard to justify. We recommend them for enthusiasts who want maximum performance without extensive porting. If your goal is a mild street engine, consider more affordable options.
- CNC-profiled intake and exhaust ports for consistent flow
- Hardened exhaust seats and phosphor bronze valve guides
- Straight spark plug location for improved combustion
Pros: Excellent out-of-the-box flow numbers; Proven reliability on high-horsepower builds
Cons: Premium price point may exceed budget builds
2. Dart SHP 180cc: Best Value
Dart SHP 180cc heads offer a compelling balance of performance and affordability. Our evaluation shows they produce strong torque from idle to 5500 rpm, making them ideal for street-driven small blocks. Owner feedback highlights easy installation and compatibility with stock valvetrain parts. The 64cc chamber yields a pump-gas-friendly compression ratio with flat-top pistons.
While the as-cast ports are consistent, some owners note that a light port match can unlock additional horsepower. For those seeking a bolt-on solution that doesn’t break the bank, these are a solid choice. However, if you plan to spin past 6500 rpm or build a race-only engine, look at higher-flow options.
- Cast from premium 355-T6 aluminum with hardened seats
- As-cast ports designed for broad torque curve
- Accepts standard rocker arms and pushrods
Pros: Excellent bang for the buck; Strong low-end and mid-range torque
Cons: As-cast finish may need minor clean-up for peak flow
3. Edelbrock E-Street 60899: Best for Budget Builds
Edelbrock E-Street heads are designed for budget-minded enthusiasts who want the weight savings and cooling benefits of aluminum. In our research, they work well with stock camshafts and intakes up to 400 horsepower. Owners appreciate the straightforward installation and the fact that they can reuse existing valvetrain components. The 170cc runner provides crisp throttle response and decent low-end torque.
However, the 1.94/1.50 valve sizes restrict airflow at higher RPMs, making them unsuitable for serious racing. If your goal is a weekend cruiser or daily driver with a mild cam, these are a great value. But for a true performance build, we recommend stepping up to larger ports.
- Lightweight aluminum construction reduces front-end weight
- Precision-machined valve seats for long life
- Compatible with stock intake and exhaust manifolds
Pros: Very affordable entry into aluminum heads; Good for mild street engines
Cons: Small valves limit top-end power
4. Trick Flow Specialties 30400001: Best for High RPM
Trick Flow Specialties 30400001 heads are engineered for racers who demand high-RPM performance. Our evaluation of flow bench data shows they exceed 280 cfm on the intake, supporting over 500 horsepower with the right cam. Owners report that the included dual springs and hardened retainers handle aggressive cam profiles without issue. The 64cc chamber works well with domed pistons for high compression.
That said, these heads are not a simple bolt-on. They require careful valvetrain geometry and may need pushrod length adjustment. For a street-driven car, the high-flow ports can kill low-end torque. We recommend them for dedicated race engines or high-performance street builds that see frequent track use.
- CNC-ported intake and exhaust for maximum flow
- Dual valve springs rated to 0.600 inch lift
- Straight plug angle for optimal flame travel
Pros: Outstanding high-RPM power potential; High-quality valve train components included
Cons: Requires careful valvetrain geometry setup
5. ProMaxx Performance 200cc: Best for Big Cams
ProMaxx Performance 200cc heads are designed for engines with aggressive camshafts and high lift. Our research indicates they offer solid flow out of the box, especially on the exhaust side. Owners appreciate the heavy-duty springs that can handle lifts up to 0.650 inch without issue. The 200cc runner size is a good match for 383 stroker engines or 350s with large cams.
However, these heads come as-cast with only a CNC bowl blend, so some owners report that a full port job is needed to unlock their full potential. They also require attention to valve clearance with high-lift cams. If you are building a serious street/strip car with a big cam, these are worth considering, but budget for additional machine work.
- Large 2.05 inch intake valves for high lift cams
- CNC bowl blend for improved flow
- Heavy-duty valve springs for up to 0.650 inch lift
Pros: Handles large cams and high lift; Good flow numbers for the price
Cons: May require extensive port matching for optimal performance
6. World Products S/R Torquer 180cc: Best for Torque
World Products S/R Torquer heads are cast iron, which makes them heavier but also more durable and resistant to detonation. In our evaluation, they produce strong torque from idle to 4500 rpm, making them ideal for trucks, towing, or low-rpm street engines. The 76cc chamber helps keep compression low, allowing the use of flat-top pistons on a 350 without detonation.
However, the iron construction adds significant weight, and the small valves restrict airflow above 5000 rpm. These are not suitable for racing or high-performance builds. If you need a budget-friendly replacement for a stock 350 in a truck or cruiser, they are a good choice. But for any performance application, we recommend aluminum heads.
- Iron construction for durability and heat retention
- 76cc chamber to lower compression with flat-top pistons
- Hardened exhaust seats for unleaded fuel
Pros: Excellent low-end torque for heavy vehicles; Inexpensive and durable iron material
Cons: Heavy weight adds front-end load; Small valves limit top-end horsepower
7. Chevrolet Performance 12370950: Best OEM+ Upgrade
Chevrolet Performance 12370950 heads are essentially stock replacement units. Our research shows they offer no significant airflow improvement over factory heads, but they are a direct bolt-on with all components pre-assembled. Owners appreciate the hassle-free installation and the peace of mind that comes with OEM quality control. They are a good option if your original heads are cracked or worn and you want to keep the engine stock.
However, for any performance aspiration, these heads will be a bottleneck. They are heavy, have small valves, and a large 76cc chamber that lowers compression. We do not recommend them for racing or even mild performance builds. If you want to increase power, look at aftermarket aluminum heads instead.
- Factory GM cast iron replacement heads
- Includes valves, springs, and retainers
- Direct bolt-on for small block Chevys
Pros: Guaranteed fit and OEM quality; Simple installation with no modifications
Cons: Very limited performance gains; Heavy and restrictive compared to aftermarket heads
Frequently Asked Questions
What size SBC racing heads should I choose for my build?
The ideal runner size depends on your engine displacement, camshaft, and intended rpm range. For a 350 with a mild cam (under 0.450 lift) and street driving, 170-180cc runners are a good match. For a 383 or larger cam, 195-200cc runners support higher rpm power. For dedicated race engines, 200-210cc or larger may be needed. We recommend matching the head flow to your camshaft’s operating range.
Are aluminum heads better than iron for SBC racing?
Aluminum heads are lighter and dissipate heat better, allowing higher compression ratios without detonation. They also offer better flow potential and are easier to port. Iron heads are heavier but more durable and cheaper, and they retain heat better for cold-weather starts. For racing, aluminum is generally preferred due to weight savings and performance gains.
Do I need to upgrade my valvetrain when installing new heads?
It depends on the heads you choose. Many aftermarket heads come with upgraded valves, springs, and retainers. However, if you are using a high-lift cam, you may need to upgrade pushrods, rocker arms, and possibly valve locks. Always check the spring pressures and installed height to ensure compatibility with your camshaft. We recommend consulting with the manufacturer or a engine builder.
Can I use stock intake and exhaust manifolds with aftermarket heads?
Most aftermarket heads have intake and exhaust port shapes that differ from stock. Some heads are designed to match stock manifolds (like Edelbrock E-Street), but many require a matching intake manifold. Exhaust headers are recommended to take full advantage of improved flow. Check the port dimensions and bolt patterns before purchasing.
What compression ratio should I target with new heads?
For pump gas (91-93 octane), a compression ratio between 9.5:1 and 10.5:1 is safe with aluminum heads. Iron heads require lower compression, around 9.0:1 or less, to avoid detonation. Use online calculators with your piston dish volume, head gasket thickness, and deck height to determine the final ratio. We recommend keeping it conservative for street reliability.
Our Verdict
After researching and comparing the top SBC racing heads, our top pick is the AFR 195cc Eliminator for its outstanding flow, proven durability, and consistent owner satisfaction. For the best value, the Dart SHP 180cc offers excellent performance at a lower price. Both are strong choices depending on your budget and power goals.
