The Edelbrock Performer LT1 complete cylinder head for 1992-1997 small-block Chevy LT1 engines delivers a direct-fit upgrade that adds about 24 horsepower over stock and raises peak power by roughly 500 rpm. It accepts factory-style self-aligning rockers and factory center-bolt valve covers, and uses stock exhaust port locations for compatibility with OE or aftermarket manifolds and headers.
