Your Recipe for Small Block Chevy Performance!
New heads are just one component of the horsepower recipe. To make it complete,
you’re going to need some more ingredients.
Cast Aluminum Valve Covers
Made from durable A319 cast aluminum, Trick Flow pent roof-style valve covers are less
prone to flex than stamped steel covers, helping to prevent oil leaks. The 4 3 ⁄16" tall covers
clear girdles and roller rockers, and can be drilled for breathers. Also important is the
Trick Flow logo that shows everybody you’re serious about your car’s performance.
Rocker Stud Girdles
These CNC-machined stud girdles help control valve lift and timing changes due to stud
flex, allowing more consistent high-RPM performance. Each stud girdle is anodized blue
and comes with high-quality mounting hardware and hardened adjusting nuts.
Track Max ® Camshafts
Give your small Chevy an even bigger power boost with a Track Max camshaft.
They are dyno-proven to produce significant power increases over the entire RPM
range, not just a particular RPM.
