I will probably take the engine heads off today(Wednesday) because I expect my head gaskets to come in within a couple of days. I will check the heads and block as best I can. How much torque should I put on the head bolts? If I need them, I will pull out the head bolts and go with studs, if that makes a difference. I was born in 1954 and worked on these old type motors growing up, and I've helped my father overhaul motors before, and we never had this type problem, however................. the motors I've worked on as a young man didn't have 11.3 to 1 compression ratio. Is this what is making a difference? Thanks for all you people who have offered advice. I appreciate it.
