I'll be installing the intake/exhaust manifold on my RAJO head soon, and want to do it right. I don't have the original RAJO manifold, but the replacement is a one piece plate with the tubes welded to it. It's flat and smooth; no warping, no rust, and no pitting. The manifold surface on the head is also in good condition. It previously had an asbestos fiber gasket, but the last time it was together was 1979, so I can't say if it worked well/leaked or not. Any thoughts on the best way to install? I thought about using a high-temp sealant as well as a gasket. Don't want to do this twice if I don't have to. Thanks for any and all input.

Copper coat both sides of the gasket and install.

Mike, that's the Permatex spray copper gasket maker? I read that's good to 500F. Also, no gasket, just the copper spray? Thanks!

Use your gasket, spray both sides of it with copper coat and install.

Thanks again. Read the first post too quickly and missed that. Much appreciated.

Clayton - I'm using a Stromberg RF carb. The manifold is home made. Really, just a cut plate with tubes welded to it; four exhaust, and one intake (in the center).
