M8 Pro Series Head
This head has a reshaped intake and exhaust port that is fully CNC ported and hand-finished. The fully CNC ported combustion chamber is also reshaped and enlarged to accept the 1mm over intake and exhaust valves. New valve guides are installed to support the custom valves with longer stem protrusion to insure the proper rocker arm to valve tip engagement – which is VERY important when using higher lift cams. New high lift valve springs are installed to achieve desired compression.
