Help me plan: My first intake swap ... EVER.

For sealing the intake bolts, I like the white Permatex thread sealant, and Permatex "Ultra" silicone for the china walls.
One more tip... sometimes it makes dropping the manifold in place a bit easier if you apply a bit of contact cement to the gasket and head surface, and glue the intake gaskets to the heads before you lower the manifold in place. This stops the gaskets from slipping down as the manifold goes on.
