Manifold gaskets

I am sure I am going to get multiple answers, just like asking about what kind of oil should I use or whether to use antifreeze or not.... but here goes.

I have received several sets of manifold gaskets from Model A'ers cleaning out their garages, etc. Two years ago I replaced the manifold gasket with a fiber gasket that had a dimpled metal facing on both sides, similar to the blown gasket I took out.

It has now failed (or actually slowly failed during the tour season last year)

I also have a solid fiber gasket available and a really old, but clearly unused gasket that is fiber but has copper bushings that actually slip into the holes a short distance.

What type do folks recommend?

Thanks,

I do the same as Bill. I use the exhaust rings when the holes line up. On my 28 I can't use a ring in the rear hole due to manifold sag of about 1/8".

If you use the gasket with metal on only one side, then the metal goes against the hotter exhaust manifold.
 
That is interesting. So on the copper gasket, the side that has the copper sticking out (like a thin bushing) goes into the manifold casting and not the block?

And the high temp exhaust coating, the last time I bought that stuff, it was like a thick paste, gritty almost like with sand in it. Is that what you are talking about ?

Thanks,

I got the sealant in a tube from Mac's, it's smooth. I've even used it on fussy headpipe to manifold connections! If it "squishes" out, just brush it off with a stiff brush, before it cures.

The late 1931 copper gaskets sold by the vendors are probably your best bet. You don't have to remove the manifolds to install, they slip in after you've loosened the attaching nuts and slide the manifolds towards you enough to slip the gaskets in. FWIW

i put the gaskets on dry no sealant and only use the copper..
never had a problem, just make sure the manifolds are straight

BUT, Yo' Ol' Dad leans krookedy, SO'S, krookedy things look straight & straight things look krookedy:confused: On my '30 Coupe, one IDIOT sed, "Your R/H tail light is lower than the L/H one, did someone step on it"?-------"I don't think so, IDIOT, I don't even have a GRUMBLE seat":D-----"Asides that, it looks straight to me";)---------"Looks like you had the *** end uf yo' coupe' straightened in TIAJUANA, did they use ADOBE fur a filler & a cheese grater fur a final finish"??:D I take NO CRAP offen' anybody & if I need to, I'll have Patti beat them up, while Buster T. eats their socks off!!!
