1. COMP Cams 850-16 Hydraulic Roller Lifters: Best Overall
The COMP Cams 850-16 are the most popular hydraulic roller lifters for BBC engines, and our research confirms they deliver consistent performance. They feature a full-circle needle bearing roller that rolls smoothly, and the metered oiling design provides adequate lubrication to the cam lobe and lifter body. Owner feedback highlights their reliability in street-driven big blocks with moderate valve spring pressures.
However, we found that these lifters may require careful pushrod length measurement, especially in aftermarket blocks. Some owners had to order custom-length pushrods. They are not ideal for extreme racing applications with high spring pressures above 400 lbs open. For most street and street/strip builds, they are a solid choice.
- Precision-ground roller with full-circle needle bearing for reduced friction
- Metered oiling through pushrod seat ensures consistent lubrication
- Heat-treated steel body and hardened link bar for durability
Pros: Reliable performance in street and mild race builds; Consistent oiling reduces wear on cam lobes
Cons: Some users report need for custom pushrod length in certain blocks
2. Lunati 72471-16 Hydraulic Roller Lifters: Runner Up
Lunati’s 72471-16 lifters are designed for performance enthusiasts who push their BBC engines to higher RPMs. The restricted oiling helps prevent lifter pump-up, a common issue with aggressive hydraulic roller cams. Our evaluation of owner feedback shows they hold up well with spring pressures up to 450 lbs open. The heavy-duty link bar adds reliability.
On the downside, some users note a slight ticking noise at idle due to the tighter clearance. They are not recommended for stock or near-stock engines where quiet operation is a priority. For a spirited street machine or mild race engine, these are a strong contender.
- Heavy-duty link bar rated for high spring pressures
- Restricted oiling reduces risk of lifter pump-up at high RPM
- Individually inspected and matched for consistent preload
Pros: Great for high-RPM street and strip use; Consistent preload out of the box
Cons: Slightly noisier than stock lifters at idle
3. Howards Cams 91125 Hydraulic Roller Lifters: Best Value
Howards Cams 91125 lifters offer a budget-friendly entry into hydraulic rollers without sacrificing essential features. They use a metered oiling system similar to more expensive sets, and owner feedback indicates they perform well in street BBC engines with moderate cam profiles. The included retaining clips add peace of mind.
However, we found that these lifters are not designed for aggressive racing applications. Some owners reported accelerated wear when used with high-rate valve springs. They are best suited for mild street builds where budget is a primary concern. If you plan to rev above 6000 RPM or use stiff springs, consider a higher-tier option.
- Affordable option with solid construction
- Metered oiling design for consistent lubrication
- Includes retaining clips for link bar security
Pros: Good value for budget builds; Works well with mild to moderate cams
Cons: Not recommended for high spring pressures over 375 lbs open
4. JEGS 800032 Hydraulic Roller Lifters: Good for Budget
JEGS 800032 lifters are a no-frills option for those converting a flat tappet BBC to hydraulic roller on a tight budget. They are heat-treated and include a standard link bar. Owner feedback shows they work adequately for low-stress street engines with mild cams and stock valve springs.
However, our research indicates occasional quality control issues, with some users needing to shim or adjust pushrods due to inconsistent preload. They are not suitable for high-performance builds or engines with aggressive cam profiles. For a basic street cruiser, they get the job done at a low cost.
- Cost-effective solution for basic hydraulic roller conversion
- Heat-treated body for durability

- Compatible with most BBC blocks
Pros: Extremely affordable; Simple design for easy installation
Cons: Inconsistent quality and durability concerns
Frequently Asked Questions
What is the difference between hydraulic roller lifters and flat tappet lifters?
Hydraulic roller lifters use a roller that rolls along the cam lobe, reducing friction and allowing more aggressive cam profiles. They also self-adjust via hydraulic pressure, eliminating the need for periodic valve lash adjustments. Flat tappet lifters slide on the cam lobe, causing more friction and wear, and require manual lash setting.
Will hydraulic roller lifters fit any BBC block?
Most BBC blocks can accept hydraulic roller lifters, but you need a camshaft designed for roller lifters (with a larger lobe profile). Some older blocks may require machining for link bar clearance or pushrod length adjustments. Always check compatibility with your specific block and cam.
Do I need to upgrade valve springs with hydraulic roller lifters?
It depends on your camshaft. Roller cams often have more aggressive lobes that require higher spring pressure to prevent valve float. Consult your cam manufacturer’s recommendations. Using stock springs with an aggressive roller cam can lead to lifter damage or poor performance.
How do I set preload on hydraulic roller lifters?
Preload is set by adjusting pushrod length or using adjustable rocker arms. Typically, you want 0.020 to 0.060 inches of preload on the lifter plunger. This is done by measuring the distance from the rocker arm to the valve tip with the lifter on the cam base circle. Follow the lifter manufacturer’s instructions.
Can I use hydraulic roller lifters with a stock camshaft?
No, a stock flat tappet camshaft is not compatible with roller lifters. The lobe shape and material are different. You must use a camshaft specifically ground for roller lifters. Swapping lifters alone will not work and can cause rapid wear or damage.
