You should not lube the end that goes in the block. You guys are argueing saying that ARP doesn't say whether to use loc-tite or not, yet almost all of you tightened your studs into the block. ARP specifically says not to do that, only finger tighten them. Part of the problem with just tightening them is that there may me a little something trapped in the bottom of the hole and it doesn't seep past the threads until later. Then you have a loose stud in there that you thought was bottomed out. With loc-tite even if it isn't bottomed out, the loc-tite will still hold it in place.
