AFR 1137-TI SBC Eliminator Racing Angle Plug Cylinder Head, Pair
AFR designed these 1137-TI SBC Eliminator Racing Cylinder Heads especially for large displacement Small Block Chevy Gen 1 engines. These feature 100% CNC ported intake, exhaust & chambers, A356 aluminum castings as well as high quality components throughout. This allows for extremely accurate as well as repeatable port location and performance.
These heads come assembled with PAC Racing springs in addition to viton valve seals. Machined bead valve locks (not stamped), hardened spring cups, as well as bead lock Stainless Steel valves included also.
Recommended for race applications or radical "Pro Street" style builds. 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 has extra machining for 3/8” pushrod clearance.
