What do you use as a thread sealant on headbolts?
Not long ago I had some work done on some BBC heads. The machinist...who was very experienced...used RTV silicone to seal the threads which kind of surprised me because it's not what ARP reccomended. However, I take his experience and advice seriously because he's assembled a LOT of engines and guarantees everything he does.
Anyway, I'd enjoy hearing what others use, especially if you've done it yourself and speak from experience. If I'm not mistaken, only a few of the BBC headbolts are actually in the water jacket.
Thanks....
