EDELBROCK PRO-PORT RAW™ CYLINDER HEADS
Pro-Port Raw cylinder heads are purpose-engineered and designed for the professional cylinder head porter and engine builder. Extra-thick decks, under-sized intake and exhaust runners, and increased wall thickness are all specifications designed for custom CNC porting. These castings are semi-machined, with finished accessory, intake and exhaust flange bosses. Optional HIP Processed castings available! This aerospace-level process delivers an incredibly strong and dense casting. Pro-Port heads can be ordered for small-block Chevy, Chevy SB2 and ROX, LS-series Chevy, big-block Chevy (conventional and spread-port), small-block Ford (including SC-1), FE Ford and Pontiac.
