I know this has been talked about several times before on this forum but what is a good sealer for the head bolts.I have some ARP thread left over from another job but not enought to do my engine. In the past i did have one engine leak past the head bolts on the two lower center ones and seap out the exhaust bolts on one head that was about twenty years ago and i think i used telfon tape and some of that arp thread sealer and never had a problem after that. I have some of that aviation permatix stuff its messy and smells bad but has anybody used that on head bolts?
