Edelbrock Performer RPM Pontiac CNC Cylinder Heads
Edelbrock Performer RPM Pontiac CNC cylinder heads have the same specifications as our popular Performer RPM cylinder heads for 1962-79 455 c.i.d. Pontiac engines, but feature a CNC-machined combustion chamber. The CNC-machined chambers result in a consistent and precise chamber for improved flow performance. Performer RPM CNC cylinder heads are available in two chamber sizes. The 87cc chamber version is ideal for 9.5:1 engines and will deliver excellent street performance on low-octane fuel. Performer RPM CNC cylinder heads with 72cc chambers are best for higher compression engines. Both are patterned after the same port flange configuration as the 1969-70 Ram-Air IV Pontiac cylinder heads.
