AFR Direct Master Warehouse Distributor - All AFR Products Available. AFR 245cc SBC Competition Cylinder Heads. AFR's 245cc "Competition" heads feature 100% CNC ported intake, exhaust & chambers, A356 aluminum castings and high quality components throughout. NPP stands for "no pushrod pinch", and this is AFR's largest 60/40 valve spacing head. These heads require shaft mount rocker arms for all applications and have extra machining for 3/8 pushrod clearance.

Component upgrade and machining options are available to customize AFR Heads to your specific build. There are many different options available for AFR heads, please view the details section below for the details on these heads. For the many other AFR heads available, and options such as upgrading springs or retainers. The Best 23° AFR Head Ever Produced!

AFR is proud to introduce the 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 the 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 the 227cc or 235cc AFR SBC product and in fact shares identical valve centerlines and rocker stud locations to both of those heads. However, unlike the 227 and 235 cc heads, this product will not accept stud mount style rockers and a shaft mount rocker system with the proper intake offset must be used. This is primarily due to the enlarged and widened pushrod pinch removing that checkpoint in the entrance of the intake allowing AFR 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. Dual valve cover bolt pattern is standard.

The exhaust ports are raised. 250 over a standard GM L-98 cylinder head.

Note: 2.125 valves will require aftermarket pistons notched for valve clearance.
