I remember replacing the manifold gaskets on both sides. When the manifolds are removed, you will find that both at the block and the manifold, you might see corrosion. Just taking the manifolds to a machine shop should do the job. Clean both surfaces well and apply a coating of sealant on both sides of the gasket. Remember that the gasket will allow for some compression to allow for a good seal. I do not remember the exact stuff I used for it. When I put new studs into the block, I decided to make my own and thread them into the block a ways. I remember that when attaching the manifolds back onto the block, Ijust tightened them as best as I could. Please! I'm no professional mechanic and I hope somebody out there has more expertise on this subject. I am a do-it-your-selver and on some jobs, I just give it my best shot with some advise from a local mechanic. Torqueing nuts and bolts, no clue!
