Big Block Chevy 454 Cylinder Head Build Kit
These kits will work with MOST aftermarket cast iron and aluminum alloy cylinder heads manufactured by companies like Edelbrock, RHS, Dart, Procomp, and Brodix with similar specs. They include just about everything necessary to assemble a bare set of cylinder heads, and get it bolted to your block! Why purchase everything separately? These kits make it easy, and there's no guessing as to which valves or springs to use together - they're all included in the kits!
*** NOTE: Valve stems are 11/32" in diameter and will not work with stock GM style heads which require 3/8" stems. For use with aftermarket cylinder heads ONLY. ***
