Frustrated

If he hit water, will the new seat cover it? 2 part hi temp epoxy in the break and follow it with pressing in a new seat. Lots of heads have epoxy in the intake ports from porting, the sealing area of the valve seat is the OD of the seat where it has a .005 interference fit with the head. The Serdi is going to cut a perfect circle at a fixed depth. The seat will fill all the area the serdi cut including the break so I think youll be OK if he seals it and them presses in the seat.
