I bolted the heads down months ago with ARP bolts and only ARP ultra lube. I remember being told a while ago by a few people that I should be fine. I was very generous with the lube but now I'm having doubts.
I'd rather re do it now while the engine is on the stand than start it up and have cooland pissing all over the place. The block was tanked, new head gaskets and the heads were milled 0.001".
Thoughts?..........

I can't believe anyone would says that installing head bolts without any type of thread sealant is a good idea. That's absolutely MORONIC.
You've got sizable bolts extending into the water jacket with fairly coarse threads - you absolutely need thread sealant on them, no questions asked.
Unbelievable.

OP - They are right, and my GM service manual confirms it.
My apologies - original post deleted.
I'll only say that my vehicle has not had any oil / coolant mixing issues over the last 15 months... (yet?)

If you have your oil tested for coolant I would pretty much guarantee you have a problem, just not severe enough to make a milkshake and make it obvious.
Far as some folks saying lube only is OK I can only guess that is because on some newer engines the bolts do not hit water and people confuse applications.

Yes lube up top and seal bottoms,may be able to do one at a time and not ruin your head gaskets in the process since you won't be separating the heads pressure from the gasket surfaces that way..

What he said. Peace of mind is something that doesnt come easy when your rebuilding an engine. those first couple thousand miles are filled with hopes and prayers (even when your not religious lol) when you know you forgot to do something. Starting that engine and knowing everything was done right helps alot.
