The Edelbrock #61029 Performer RPM Cylinder Head for 1965-76 Oldsmobile 400, 425, 455, 488, 495 Cu In V8 engines with hydraulic flat tappet camshaft is a perfect performance upgrade for big-block Oldsmobile powered street machines and muscle cars. This aluminum cylinder head supersedes the 60519 Oldsmobile head and features a redesigned 77cc combustion chamber, larger intake ports 218cc volume and exhaust ports 138cc volume, with intake valves 2.150” and exhaust valves 1.680”, refined bowl blending for improved flow.
The #61029 Performer RPM head has improved accommodation for a factory-style mechanical fuel pump with spark plug locations moved slightly towards the exhaust valve for optimized combustion. Intake and exhaust ports have been improved over previous designs, and extra material has been added above the intake port for head work.
