Silicone as an exhaust manifold sealant??

So I was car chatting with a guy this evening. As usual I'm going on and on about cars because if you give me the idea you want to car talk, then you better pull up a seat and get you a snickers bar, you're going to be here awhile.

I'm building a hyper pak slant six for a valiant wagon. I took the head to a machine shop on march 5, 2020. A little after that, the shop closed due to the whole thing with covid-19. So now its the end of June and the shop is still closed and I can't ever find anyone there and they still have my cylinder head.

So I mentioned that I am going to put my slant six Clifford headers and intake on a different slant that is a good running stock original engine just to get the car running.

So I don't want to spend good money on a Clifford brand intake/ exhaust gasket because the engine is temporary until I can get my performance engine built.

I mentioned I am going to use a standard fel pro gasket with the Clifford stuff but I'm not sure if it will hold up.

He suggested using the felpro gasket with silicone. Standard household silicone.

What do ya think??

Not hardly. Put it on dry, it will last plenty long for what you want.
