No, not what I'm saying. Why all the butt hurt. The two I've seen crack were at the outside bolt holes. I know, for a fact that one of them was sitting on the dowel pin when he torqued it down.
If they are cracking at the bolt bosses that's a human fault most of the time.
If they are cracking from the seat out...I've seen a hundred of those, even in Pcar heads. Put a seat in it and forget it. Come to think of it, the only W-2 heads I've seen crack at the intake seat are the early closed chamber head. My buddy has a set. I'll get some ductile iron seats ( or make a few), install them and let them run.
