Cavitation check

Thanks for the great pic of why the intake seat replacement is usually never going to work. The coolant passages are just too close. Now I don't know if the new offshore heads will react the same. They are supposed to be thicker but I'm not sure if they are better in this area or not.

Who sells the offshore heads? I tried the guys at Diesel Cast Welding this morning, They've run out of new heads and they aren't going to get any more cast as the market for them has slowed.
