Get the performance you need with the Chevrolet Performance Cylinder Head Assembly. Cylinder heads sit on top of the cylinder block to form the combustion chamber, and have ports for the fuel/air mixture and exhaust gases to travel through. The 572/620 Bowtie cylinder head assembly is made of 356-T6 aluminum and features thick deck surfaces and high-velocity airflow passages. The head is manufactured to precise machining tolerances, and is assembled with 2.250-inch/1.880-inch 11/32-inch stem valves, valve spring retainer and locks, valve springs for hydraulic roller cams for up to .632-inch lift, valve seals, valve spring shims, rocker arm studs, valve spring locators, and steel pushrod guide plates. It is not recommended for engines smaller than 572 cid, will work on Mark IV and Gen V/VI blocks, and does not include heat risers. 3/8-inch pushrods, an intake gasket, bolt kit, head gasket, and head bolt kit are required. No matter what you're driving or what you're building, Chevrolet Performance has a wide range of engines, parts and other accessories to help you fulfill your project-vehicle dream.
