The Edelbrock #60859 Small-block Chevy cylinder head is designed for 1987-95 Throttle Body Injected (T.B.I.) and Tuned Port Injected (T.P.I.) 5.7L S/B Chevy engines originally equipped with center bolt valve covers. Performer center bolt cylinder heads are 50-state street legal and accept factory center bolt valve covers. The intake bolt pattern utilizes the 1987-95, 73° angle on the two center bolts. Will maintain stock compression ratio when used with the recommended head gasket. The Edelbrock Performer heads are perfect for street performance, daily drivers, street rods and muscle cars where seat-of-the-pants performance is needed. They also feature the highest quality intake and exhaust valves and valve springs.
