Check to see if the threads in the block are stripped also.... if not, just buy new bolts. if so, try to tap them again and buy new bolts.


BTW: how much are you paying to P&P the head?

^^ And keep your fingers crossed in the process

you MIGHT be able to have a machine shop do a helicoil in the head. i dont know if they would hold with the head stud torque tho...

Wow. That pretty much blows. See if there is a way to get some kind of a prying objectamajiggie between the head bolt washer and the head, and then try to unscrew the headbolt. Hopefully, the bolt will back out. Otherwise, pull the motor and try to pull it all apart when you can get more leverage on everything.

Again, that pretty much blows.

Sears sells a rounded bolt head socket. Hammer it on and it digs into the bolt head and twists them out. I've used it a couple of times and it works well, probably your best bet at the moment.

Who worked on your head last, that they stripped the heads?
