Is there such a thing....

Yes.



It makes no difference. If they seal.

That is what I question.

Intake gaskets are not .040" pieces of paper. Why is that? If .040" of paper works so well, why not use that gasket form in that position?

'Thick' is not necessarily better.

I had no intention of starting a 'which oil is better' scratchin' post. Paper gaskets in a carburetor flange position seem unacceptable to me. That they are used 'all the time' and 'everybody likes 'em' doesn't mean anything.

C'est la vie



Thank you. That is the type of information I was looking for. Too bad the outline of their PN-4154 does not follow the outline of every manifold and carburetor made.

Then just get some high quality ones and be done with it. Here. That's all this company makes is high quality gaskets.
