Default Intake manifold gasket.

I got some oil that looks to be coming out of one of my intake bolts or between the head and intake in that area. I'm assuming the gasket busted from boost, #15. What is the best intake gasket for boost and what special things need to be done like sealant around the runners?
Thanks. See my sig for car info

I put sealant on the treads that touch oil and paint a shellac around the intake ports. Works for me.

Real thin coat and don't over tighten the intake bolts.

I use 3m weather stripe adhesive. put it on both sides of gasket and on the head and intake, seals anything!

I had a different washer on the leaking one. Turns out that the sealant on that one was not doing its job that well. It was only in the head about 1/4" at the most, had indifferent washer on it that didn't allow it to go in all the way. Got a longer bolt and put some sealant on it. If it doesn't hold I'll pull the manifold.
