|AFR 227cc SBC Racing Cylinder Head|
|High flowing AFR 227cc intake port small block Chevy angle plug cylinder heads have 100% CNC ported intakes with 100% CNC ported 66cc combustion chambers and 80cc exhaust ports with a 3/4 thick head deck (ideal for nitrous or blower applications). Standard valves are 2.100 intake and 1.600 exhaust with AFRs hardened ductile iron interlocking valve seats. The 227 has 60/40 valve spacing and piston valve pockets should be checked. The exceptional flow characteristics and 23º valve angle make this the perfect head for 350 to 434 cid engines in drag cars, sprint cars, and late model oval trackers operating from 4500 rpm and up. AFR offset stud girdles are the only special parts required. Some applications require shaft mount rockers for durability and reliability of valve train components. Not recommended for street use, unless shaft mount rocker is used.|
