THESE GASKETS ARE DESIGNED TO BE PUT ON DRY. ANY SEALER YOU PUT IN THERE WOULD ONLY BURN AND CAUSE LEAKING PROBLEMS

Any gasket that's exposed to manifold vacuum or exhaust gas needs to be installed dry. A tiny vacuum leak will draw sealer into the engine, and probably create a permanent leak, and no gasket sealer I've used in the past 50 years is designed to seal exhaust heat.

I certainly would have tried it the other way first. I was looking through the manual, but couldn't find info on installation. In fact I couldn't find any info about the manifolds. I'll take a closer look today. However, anyone have some more tips. Like bolt torque specs, and installation sequence. I would just guess going from the center bolts and working alternate sides out slowly, tightening a little as I go. By the way, this is my first restoration.
