When porting bigger is not better..(TIP) When porting press a bottle cap or plug tightlly in the valve seat area to protect the seat,you are going to spend a lot of time porting ,,spend the time to protect your seats by making a protector..when working near the seat use duct tape on the seat at a minimum..
