Sounds like you've got head bolt problems, I retapped mine 1/4 20 and jb welded it into the block! Runs great!
No problems, I have 4 engines and all the studs (intake, exhaust, head) are 6mm. I know eventually I'll need to replace one and would like to have it handy in the shop. I like to keep extra supplies in the shop just in case. This way I don't have to run around town or wait a week for shipping. Just makes sense to me...You never know what may happen. :crash::crash:
