Thanks Ted! I have a really hard time with the search options and posting pictures with the new software. If I could navigate thru the search better, I would not have to post so many "new topics" that are already covered.

Bolt length will not change if gaskets are not used.  A thin film of red high temperature RTV in lieu of a gasket wouldn't hurt.
Here's the link to a previous thread discussing the truck exhaust gaskets which did not use any sealer on them.

Your right, I got off track on that one. Looks like I hijacked my own thread. I will clean that post up with the "edit option".

I don't think anyone is referring to the intake manifold.  I think we're just talking about the exhaust manifold aren't we?

Ted,

If I understand correctly, you favor no gaskets when using cast iron exhaust manifolds on cast iron heads. John Mummert recommends (4) 1 1/2" bolts and (3) 2" bolts to install his manifolds. Would this not using a gasket change this length?

just finished installing ram horn manifolds, these are on ally heads. i found i needed 3 at 1.5" and 4 at 1.75"  i tried 3 at 1.75" and 4 at 2" but these bottomed out.

Now as my memory is coming back, I had to whittle/file a contour in the manifolds over the spark plugs in order to get a plug socket on the plugs in some locations.

Maniseal is a ceramic gasket sealer, perhaps you can use that on the threads?

Why any anti seize, grease, etc. No manufacturer fits grease or anti seize.

Always cold Heads with Aluminium with every thing you do with them. 38*C and below.
And how about tensions,its easy to pull threads with aluminium, grease won't change that.

FWIW, the copper product I've always used on ground and terminal connections came out of the electrical industry. I'm sure it's CU-AL rated by UL and CSA. And given how much galvanized steel we used, I'd be surprised if it was a problem there, either.

And thanks to whoever posted that adding a "tag" let one post from Safari.
