Edelbrock Performer RPM Aluminum Chev BB Head
Using high efficient ports and state-of-the-art combustion chamber shapes, these heads offer improved performance throughout the rpm range for great throttle response and top end horsepower. Top quality features include threaded inserts in rocker studs and exhaust bolt holes for superior strength and durability. Cast and machined at Edelbrock's manufacturing facilities in the USA.
Assemblies feature 2.190"/1.880" stainless steel valves, 1.550" dual springs, 7 deg. retainers and locks, studs, and guide plates.
Note: spark plug is closer to center of bore, will interfere with most high-dome pistons. Use pistons specifically designed for Edelbrock heads for high compression applications.
