Best stuff you'll ever come across for gaskets. As long as the ports line up, you don't have to worry about anything else when using that stuff.
It's like a rubber cement. Apply it to head, and gasket, let it tack up for about 10 minutes, and install it with a rubber mallet.
Put it on the intake and intake side of the gasket, let it set up, bolt the intake on. If you have ANY leak after doing that, there's a MAJOR issue with your head or intake.
I blew out an entire set of intake gaskets with RTV on them at 33 PSI of boost... Put that stuff on, and no more issues.
That stuff works, but you still have to contend with mismatch between the upper intake bolt holes of the head and the gasket because you have to use the 1275 Fel-pro gasket which doesn't have the upper bolt holes.
