Info

This head is designed to maximize the potential of GMS race oriented LSX block. it is also compatible with all previous versions of the engine. The true canted valve design offers the utmost in port flow and combustion efficiency possible with a two valve design. The head uses the GM SB2 valve cover footprint required by the added width of the canted valve layout. The stock exhaust bolt pattern is retained. Like all Edelbrock Pro-Port Raw heads, they will require professional preparation, including CNC porting to the port design of choice. Valve guides are included but not installed. This head has been HIP processed to increase density and provide the heads with extreme durability.
