Your choice of ported Swirl or G-head. We inspect and pressure check the cylinder head prior to machining. The combustion chambers are reworked, the intake/exhaust ports are extensively ported for better flow, 4-angle competition valve job and new backcut +1mm size valves with either slider or roller cam springs, retainers and keepers. Camshaft, lifters and followers are available upon request. This cylinder head will support applications well over 400HP.
