    This Cylinder head assembly is identified by the Chevrolet "Bowtie" logo engraved on the end surface of the cylinder head, this replaces the "GM Performance Parts" logo that was formerly used. This head is assembled using Chevrolet Performance "blue" beehive-style valve springs, part 809-12625033, using compatible spring retainers, seats and split key locks. These components were changed to provide maximum durability and stability at the sustained RPM typically experienced in circle track racing.

  • Specifications:

    Manufacturer's Part Number:

    This Chevrolet Performance Small Block Chevy "Fast Burn" Aluminum Cylinder Head has the highest performance potential of any 23° small block head developed by Chevrolet using flat top pistons. It adds 30 bolt-on horsepower when used on the Chevy ZZ4 crate engine. 62cc fast burn combustion chambers produce higher cylinder pressures by burning more of the available fuel before the piston starts its power stroke downward. Head surfaces and rocker rails are CNC-machined to exact tolerances, thus eliminating the need for blueprinting. D-shaped ports and runners require no additional porting (but can be for all-out racing applications). This cylinder head fits 1958-Present small block Chevy 283-400 engines with a conventional water flow design (cannot be used on LT1, LT4, or LS1 engine with reverse water flow). The cylinder head is completely assembled with valves, springs, retainers, and 3/8'' rocker studs that require the use of self-aligning rocker arms.
