Machinist's advice sought

[Verne_Frantz]

Thanks for the opinions. As for the piston, that was my plan (as long as its not cracked). The stud broke for two reasons. One is that it was weakened by the pin hole and two because the Intake valve head got caught under the exhaust valve. I don't plan on drilling the new stud.
As for the crack, I'm still not convinced it might cause more problems. It can't go anywhere because it ends at the pin hole and there should be no side to side thrust on the stud. Once the old stud is removed, I'll see how far down the threads go.
