Buying Guide

Match bolt type to engine family

Confirm compatibility with your engine (LS, Chevrolet small-block, Toyota/Lexus, non-VVT camshafts) to avoid improper thread pitch, length, or head style

Check torque and stretch specs

Choose bolts or retainer kits with documented torque or torque-to-yield/stretch characteristics to ensure correct clamping force during installation

Prefer reputable OEM or OE-quality brands

Brands with automotive parts experience (Fel-Pro, Michigan Motorsports) typically provide consistent fitment and documentation useful for repairs

Inspect material and coating

Look for high-strength alloy construction and corrosion-resistant coatings to withstand thermal cycling and coolant exposure in cylinder head applications

Consider included components and packaging

Sets that include matching washers, spacers, or thrust retainers reduce the risk of missing parts and simplify reassembly for camshaft or head jobs
