prepping motor for install
I found high temp rtv between the intake and heads.
im sure there wont be any vacum leaks but im concerned about performance? I dont feel like taking the intake off to correct that issue but will try to scrape or cut most of it off. engine runs on dyno fine but im sure i can get better flow without the RTV in the way. whats the best approach for the removal of the RTV without disturbing the intake? pics are of each side. same amount just about everywhere. see pics: .JPG) .JPG) .JPG)

Leave it alone, it won't do squat to remove it. There isn't any good way to get it out other than what you can pick off via the plenum opening.

It is not uncommon for some builders to skim the intake ports with a coating of RTV when they do the water jackets and front and rear mating surface.
We don't, but we do apply, to the head side, a light coat of weatherstrip adhesive and stick it on the head about 15 minutes before mounting the intake. That way the stay in place when mounting the intake.

I am sure a "light coat" would be much easier than some of the work I have come behind.

A few dabs will do it.

I never use weatherstrip adhesive PITA 4 sure to get off..... i also never use silicone around the intake ports or around the water jackets.....Only place i use it for intake is at the ends where the rubber ends would normally go and i run it up about 3/8" up on the head from the block..There are other ways to hold the intake gaskets in place besides glue
