working on assembling the engine for my pulling truck and was putting the first head on today and had another stud pull out of the block

. for those of you that dont know this is the third time it has happened. the other two have helicoils in em. so what should i do just helicoil this one and hope again that no more do it or just helicoil the whole damn block? it has been well lubed everytime so thats not it. also whats a partial filled block weigh? scrap is what $9-10 a hundred.

I didn't say anything, but I knew that was going to happen. I used helicoil before and wasn't to impressed with it.
Sorry about the block though, I'd still like to know why this happened to ya, I've never heard of anyone having this problem:fustrate:
