These Edelbrock Performer LT1 cylinder heads are designed for the 1992-97 LT1 engines. They produce approximately 24 hp more than factory-stock LT1 heads, and raise peak power levels by 500 rpm. They work with stock or aftermarket self-aligning roller rocker arms. These Edelbrock Performer LT1 aluminum cylinder heads feature threaded inserts in the rocker studs and exhaust manifold bolt holes for superior strength and durability, plus hardened seats, bronze valve guides, and fully machined valve cover rails for a more consistent gasket seal. They offer improved power throughout the rpm range for greater throttle response and top-end horsepower. The intake and exhaust runners are CNC-machine profiled for superior flow and performance.
