Perfect for Higher Compression 1500-6500 RPM

This Performer RPM cylinder head is designed for outstanding performance gains in 1962-77 389-455 c.i.d. Pontiac engines. They are patterned after the 1969-70 Ram Air IV Pontiac cylinder head. This head has 72cc combustion chambers for higher compression engines and is perfect for street performance, daily drivers, street rods and muscle cars where seat-of-the-pants performance is needed. This cylinder head delivers great throttle response and power from 1500 to 6500 rpm. Bare heads will have valve guides and seats installed, but will require final sizing and a valve job to match the valves you will be using.
