Default Re: Block to Manifold sealer for Alcohol SBC?

Ditto on the Permatex Ultra Black - use it for just about everything. Had one issue in the past on a Brodix intake that kept blowing oil out the end rails. No matter what I did, it wouldn't hold. What I found out and had corrected with a little milling work was that the gap at the end rails wasn't large enough. The gap was probably on the order of .015-.020, we took another .020 off the rails, used the Ultra Black and never had another issue with it. Oh and we run alky too.
