my intake manifold gasked instructions say to apply a think coat of sealer around the intake ports on the inside and topside of the gasked to prevent vaccume loss, will black RTV work for this?

On my last couple intake swaps, I ditched the ends gaskets in favor of a 1/4" thick bead of black RTV. This was recommend to me by a very reputable Chevy engine builder...

As a matter of fact, some GM manuals state to do the same. Don't use the end gaskets at all, just make sure the bead is thick enough.

I use copper instead of black. It's impervious to every chemical in the engine and is high temp as well.
one of the reasons the RTV on end gaskets is good is when heads and blocks have been milled, changing that end gap. the RTV don't care what gap it is... oh, and i use the black too....
I never use the end seals anymore after a few of them popped out and caused mucho leakage--.I used "Ultra Blue" permatex,its supposed to be more oil resistant than the others--but it comes in all your favorite colors--Ultra Black-Ultra Blue-Ultra Copper-Ultra Grey-Red High Temp--Ive used them all with good results---I wonder when they will come out with "Ultra Clear",or "Ultra Silver"?? /forums/images/graemlins/rolleyes.gif /forums/images/graemlins/screwy.gif
