Changed the intake manifold, now there's an exhaust leak between manifolds.

I looked up those Remflex gaskets. It might be the right move but I'd have to wait for them to get here. I'll decide by tomorrow. My plan was to try again with the replacement steel gasket and a good layer of Permatex #2 non hardening sealer on each side. But I will keep those Remflex gaskets in mind for the next time I need them.
