It seems that there are many different opinions about what to use to seal the head bolts (or in this case, studs) are sealed. Some say just use anti seize and some recommend something else. Full disclosure; the threads in the block were chased with a regular tap way back when. I have used High Tack in the past on banger motors with a 100% success rate but I have never even heard that mentioned as an option. BTW, I know that studs aw only to be installed finger tight. To be honest, I can’t see any reason why teflon tape wouldn’t work (for studs) or plain old Rector Seal #5 (for studs or bolts. I like something with a little more of a positive seal than just Anti seize. I have read Ron’s book (several times) and I’m pretty sure that he just uses anti seize (I did not double check that however, I’m going by memory here) but I think Ron’s motors are taken apart so often that it is not such a big deal for him. I recently pulled the head off a flathead Willys motor and found that the head gasket had failed because the steel head gasket had rusted to the point of failure. Now, to be honest, the head has been on there for 40 years so there’s nothing to complain about but who knows, if proper sealing had beeen done it might still be going strong.
