Notes

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. Heads have CNC intake ports, combustion chambers and exhaust ports, stock exhaust port locations, and the spark plug angles have been modified to produce a smooth flame front.
