1. Comp Cams Ultra Pro Magnum Roller Rockers: Best Overall
The Comp Cams Ultra Pro Magnum roller rockers are a top-tier choice for serious SBC builders. In our evaluation, these rockers deliver outstanding performance thanks to their precision needle-bearing fulcrum and heat-treated chromoly steel construction. Owner feedback consistently praises their durability even under high spring pressures and high-rpm use. The available 1.5:1 and 1.6:1 ratios cover most street and strip applications.
However, these rockers come at a premium price, which may not suit budget-conscious builders. Additionally, some users reported that the included adjusting nuts could be of higher quality. If you are on a tight budget or building a mild street engine, you might consider a more affordable option. But for those seeking maximum reliability and performance, the Ultra Pro Magnums are a solid investment.
- Precision needle-bearing fulcrum reduces friction and extends life
- Heat-treated chromoly steel body with heavy-duty trunnion
- Available in multiple ratios and stud sizes for SBC
Pros: Excellent build quality and consistent geometry; Proven in high-horsepower builds
Cons: Premium price point
2. Scorpion Racing Products SBC Roller Rockers: Best Value
Scorpion Racing Products offers a compelling value proposition for SBC owners. We compared their roller rockers against similarly priced competitors and found that they use quality 4340 chromoly steel and full needle bearings. Owner feedback highlights the ease of installation and the included poly locks. For a street performance build, these rockers provide noticeable gains without breaking the bank.
On the downside, some users noted that the pushrod cup depth can vary, leading to geometry issues that require shimming or different pushrods. This may add extra effort during installation. If you are building a high-stress race engine, you might prefer a more premium set. But for most street and mild strip applications, the Scorpions deliver excellent value.
- Full needle-bearing design for reduced friction
- 4340 chromoly steel body with black oxide finish
- Includes poly locks and adjusting nuts
Pros: Great balance of performance and affordability; Complete kit with all hardware
Cons: Some reports of inconsistent geometry out of the box
3. Harland Sharp SBC Roller Rockers: Premium Build
Harland Sharp roller rockers are a favorite among engine builders who demand the best. In our research, these rockers stand out for their use of 8620 steel, which is heat-treated and shot-peened for maximum strength. Owner feedback often mentions their longevity even in high-rpm endurance applications. The precision machining ensures consistent geometry, reducing valvetrain wear.
The main drawback is the cost; these are among the more expensive options. Additionally, some users found the included hardware to be basic for the price. If your budget is tight, you may find better value elsewhere. However, for a no-compromise build where reliability is paramount, Harland Sharp is a top contender.
- American-made from 8620 steel, heat-treated and shot-peened
- Full needle-bearing fulcrum and roller tip
- Precision-machined for consistent geometry
Pros: Exceptional build quality and longevity; Excellent customer support from manufacturer
Cons: Higher price point
4. Proform SBC Roller Rockers: Budget Pick
Proform roller rockers are an entry-level option for SBC owners on a strict budget. We evaluated them against more expensive alternatives, and while they lack the features of premium rockers, they still offer a roller tip and investment cast steel body. Owner feedback indicates they are a noticeable upgrade over stock stamped rockers for mild street engines.
However, these rockers are not designed for aggressive camshafts or high-rpm use. Several users reported premature wear on the roller tip and trunnion when used with high spring pressures. If you plan to push your engine hard, invest in a stronger set. But for a basic rebuild or budget performance build, the Proforms get the job done.
- Investment cast steel body for strength
- Roller tip reduces valve guide wear
- Affordable option for budget builds
Pros: Very affordable; Reduces friction compared to stock rockers
Cons: Not suitable for high spring pressures or high RPM; Some reports of tip wear over time
5. Summit Racing SUM-G6800 SBC Roller Rockers: Reliable All-Rounder
Summit Racing’s house brand roller rockers are a solid middle-ground choice. We compared them to other mid-priced options and found that they use 4340 chromoly steel and full needle bearings, similar to more expensive sets. Owner feedback is generally positive, with many noting easy installation and reliable performance on street/strip engines.
The main limitation is the fixed 1.5:1 ratio, which may not suit those wanting a higher ratio for more lift. Additionally, some users mentioned that the included poly locks could be tighter. If you need a 1.6:1 ratio or plan to run aggressive springs, look elsewhere. But for a dependable 1.5:1 set, these are a great value.
- 4340 chromoly steel body with black oxide finish
- Needle-bearing fulcrum and roller tip
- Includes poly locks and adjusting nuts
Pros: Good quality for the price; Complete kit with hardware
Cons: Limited ratio options (1.5:1 only)
6. Lunati Voodoo SBC Roller Rockers: Race-Ready
Lunati Voodoo roller rockers are aimed at racers seeking more valve lift without changing camshafts. We researched their performance claims and found that the 1.6:1 and 1.7:1 ratios can significantly increase lift. Owner feedback from track users indicates they perform well in high-rpm environments, though some noted that they are not as robust as higher-priced competitors.
However, durability concerns arise when used with very high spring pressures. Some users reported trunnion wear after extended use. Additionally, fitment can be tight on some cylinder heads, requiring clearance checks. If you are building a serious race engine, you might want a more proven brand. But for occasional track use or a hot street car, the Voodoo rockers offer good performance at a moderate price.
- High ratio options for increased lift
- Full needle-bearing design
- Lightweight body reduces reciprocating mass
Pros: Available in higher ratios (1.6:1, 1.7:1); Good for high-rpm applications
Cons: Not as durable as premium brands under extreme use; Some fitment issues reported with certain heads
7. Howards Cams SBC Roller Rockers: Solid Mid-Range
Howards Cams roller rockers are a budget-friendly option for mild SBC builds. In our evaluation, they offer basic roller rocker features with an investment cast 4340 steel body. Owner feedback is mixed: some users are satisfied with the performance on low-stress engines, while others experienced issues like loose tolerances or premature wear.
The main concerns are durability and consistency. Several owners reported that the rockers did not hold up well under moderate spring pressures, and some had to replace them after a short time. If you are building a high-performance engine, skip these. But for a stock replacement or very mild upgrade, they may suffice, though we recommend spending a bit more for better reliability.
- Investment cast 4340 steel body
- Roller tip and needle-bearing fulcrum
- Includes poly locks
Pros: Decent build quality for the price; Good for mild street engines
Cons: Not recommended for high-performance builds; Some reports of inconsistent quality control
Frequently Asked Questions
What ratio of SBC roller rockers should I choose?
The most common ratios are 1.5:1 and 1.6:1. A 1.5:1 ratio is standard and provides mild lift increase. A 1.6:1 ratio increases valve lift by about 6-7%, which can improve airflow and power, but may require checking piston-to-valve clearance. For aggressive cams, higher ratios like 1.7:1 are available but require careful valvetrain geometry verification.
Do I need to change pushrods when installing roller rockers?
Often yes. Roller rockers can alter the valvetrain geometry, so you may need different length pushrods to achieve proper rocker arm geometry. We recommend measuring pushrod length after installation and using an adjustable pushrod checker to determine the correct length. Many kits include pushrods, but verify compatibility.
Are full roller rockers better than roller tip only?
Full roller rockers (with a needle-bearing fulcrum and roller tip) reduce friction more than roller tip only designs. They are generally more durable and allow higher RPM. However, they are more expensive. For high-performance or racing use, full roller is recommended. For mild street engines, roller tip rockers can be a cost-effective upgrade.
Will SBC roller rockers fit all small block Chevy heads?
Most aftermarket roller rockers are designed to fit standard SBC heads with 3/8 in. or 7/16 in. studs. However, some heads with raised runners or offset rocker arms may require specific offset rockers. Always check the manufacturer’s fitment notes and measure clearance, especially with aftermarket heads or high-lift cams.
How do I adjust valve lash with roller rockers?
Roller rockers typically use poly locks and adjusting nuts. The procedure is similar to stock: set the engine to TDC on the compression stroke, loosen the rocker nut, insert a feeler gauge between the rocker tip and valve stem, tighten the nut to spec, then lock the poly lock. Follow the camshaft manufacturer’s recommended lash settings.
