I mean when I was torqueing them down they stripped out. I have the D16Z6 in a 93 EX. When I pulled the head bolts out one had a 1/4" inch of the threads from the block on it and the other had 1 " of threads. Wasnt sure how I could fix it. Got any ideas? Figured since the block had 155K on it I would just go ahead and swap it.
