AFR is proud to introduce our new 245 NPP (no pushrod pinch); best suited for max effort applications, but larger displacement 427+ pump gas engines could consider this head as well. This exciting product represents our best flowing 23° SBC head to date and while flow numbers may reflect a very good 18° head of the past, this head is still a conventional direct bolt on non-raised runner intake port configuration. It will drop on your 23° shortblock as easily as our 227 or 235 SBC product and in fact shares indentical valve centerlines and rocker stud locations to both of those heads. However, unlike the 227 and 235 heads, this product will not accept stud mount style rockers and a shaft mount rocker system with a .180 offset intake lifter is required. Larger diameter 3/8" pushrods fit without additional clearancing. This is primarily due to the fact we enlarged and widened the pushrod pinch removing that checkpoint in the entrance of the intake allowing us to design a port with a more direct shot at the back of the valve that also has a more consistent cross sectional area and velocity profile. In addition, this head comes standard with a 3/4 inch deck, 2.125 intake and 1.600 exhaust. The exhaust port is raised .250 over GM L98 head(see footnotes here). If you are unsure if this is the right AFR head for you, we encourage you to contact us directly to discuss your combination.
