Item Description
|
AFR 245CC SBC ELIMINATOR COMPETITION ALLOY HEADS COMPLETE CHEV SB AFR1138 AFR 245cc NPP SBC Eliminator Racing cylinder heads have been designed for use in max effort applications, but would also be a consideration for larger displacement 427+ pump gas engines. They feature 100 percent CNC-ported combustion chambers, CNC-ported exhaust ports, and CNC-ported intake ports. They are a conventional direct bolt-on, non-raised runner intake port configuration. AFR 245CC Eliminator heads share identical valve centerlines and rocker stud locations to the SBC 227 and 235 product lines. Larger diameter 3/8 in. pushrods will fit without additional clearancing. They also come standard with a 3/4 in. deck, 2.125 in. intake, and 1.600 in. exhaust valves. AFR 245cc NPP SBC Eliminator Racing cylinder heads are available bare or assembled and represent one of the best flowing 23 degree heads to date. |
