19417592 - Chevrolet Performance Small Block Chevy "Fast Burn" Aluminum Cylinder Head - Complete (1 head)

Pricing: $1,378.00


This head can be used on any 1958-2000 283-400ci small block Chevrolet V8 engine with conventional water flow design, but this head cannot be used on any LT1, LT4, or LS1 engines that are designed with reverse water flow.

The all new 23 degree small block cylinder head has the highest performance potential of any 23 degree small block head developed by GM.

The Fast Burn head combines new technologies with the best of GM motorsports and production cylinder head technologies. The design creates tremendous power on engines from 35 to over 400ci.

The name Fast Burn refers to the heads ability to quickly and completely burn the air furl mixture, resulting in higher cylinder pressures and more power. The shape of the combustion chamber is designed to accomplish this Fast Burn with flat top pistons, so flat top pistons are recommended with this cylinder head. It is not recommended that the combustion chamber be modified or reshaped as this could decrease the efficiency of the chamber.

The head is designed with a .400" deck. This new technology removes material from other portions of the head allowing for considerably larger ports and water jacketing. The deck also provides unsurpassed clamping force for cylinder head gasket retention. The super rigid .400" deck thickness can be machined down to .340" safely for all-out performance applications and higher compression. Other ways to adjust compression ratio with the Fast Burn head include top of piston design and piston installed height.

Unlike the GM Performance Parts Bow Tie heads and most aftermarket performance heads, this head requires no additional porting for maximum performance. In the past the industry has added material to heads to allow substantial porting, which can result in poor out of box performance and additional cost. The Fast Burn head utilizes GM Performance Parts Cast-Ported technology, which means that improvements in flow combustion and cylinder fill were incorporated into the machining tooling, achieving maximum performance out of box. Additional porting is recommended for all out race applications. Polishing of combustion chambers and exhaust ports is acceptable. All Fast Burn heads are CNC machined to exacting tolerances, thus eliminating the need for the blue-printing of machined tolerances, resulting in a cost savings and unsurpassed out of box performance.

This head has taller than typical rocker cover rails, providing exceptional clearance for rocker arms and valve train supports typically used in all out performance applications. The rocker rails are CNC machined for superior rocker cover gasket sealing. Front head faces are drilled and tapped for typical accessory drive bracketry.

The Fast Burn head accepts both center bolt and early style four bolt flange mount valve covers.

Signature etched with Chevrolet Performance logo. Intake manifold mating surfaces are drilled and tapped for both Vortec and conventional raised port style manifolds.

Vortec style manifolds are recommended.

D shaped 78cc exhaust port and runners provide adequate flow for applications well in excess of 500hp. Raising the top of the intake valves provides a better line of sight through the port and onto the back side of the intake valves.

The 62cc fast burn combustion chambers produce higher cylinder pressures by burning more of the available fuel before the piston starts its power stroke downward. By more completely using available fuel, the engine produces more power per quantity of fuel.

The 2.00" hollow stem lightweight intake valves are utilized to reduce loads on valve train systems at high rpm's.
