Well I spoke to Terry, looks to be that he has a number of heads sitting in his shop. He'll be taking some measurements than we'll basically go from there. The porting will be computer generated to exact dimensions needed to make consistent power gains across the board. Most power gains will come from the CNC process though 5angle valve job will also compliment the heads for increase power, swirl and smoother entry of air + a much better seating of valves.
Larger valves can be done for those that need it.
