Edelbrock Performer RPM Small-Bore Cylinder Heads are engineered for use with 265, 283, 305 and 307 cid small-block Chevy engines produced from 1954-2003 with 3.736″ to 4.000″ bores.
These cylinder heads have the same great features as every Performer RPM series cylinder head, such as a thick deck, extra thick port walls, high-flowing ports, ductile iron seats, and high-quality rocker studs. The Performer RPM Small-Bore cylinder heads feature state-of-the-art compact combustion chambers and highly efficient ports that offer improved performance throughout the rpm range for great throttle response. Other top-quality features include threaded inserts in rocker studs and exhaust bolt holes for superior strength and durability, as well as manganese-bronze valve guides.
NEW FEATURES:
- Valve spacing has been reduced to 1.817″ to accommodate the smaller bores
- Retains the stock straight spark plug angle and exhaust flange bolt pattern for ease of use with factory style exhaust systems
- Utilize the early Gen 1 (1959-86) valve cover bolt pattern
- Designed, tested and cast from A356 aluminum and heat treated to T-6 specs in Edelbrock’s facilities in Southern California to guarantee you get the best from a name you can trust
