Performer RPM CNC cylinder heads have the same specifications as our popular Performer RPM cylinder heads for 1962 to 79 455cid Pontiac engines, but feature a CNC machined combustion chamber. The CNC machined chamber results in a consistent and precise chamber for improved flow performance. Performer RPM CNC cylinder heads are available in two chamber sizes. The 87 Cubic Centimeter 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 72 Cubic Centimeter chambers are best for higher compression engines. Both are patterned after the same port flange configuration as the 1969 to 1970 Ram Air IV Pontiac cylinder head.
