Looking for something under .030 head gaskets for my 416 4.070 bore build that will only be 10.2 to 1 or so compression.

Most sites list the P4120094 .028 compressed gaskets at 4.06 bore, which will not work for me. But some list that as 4.125 bore which I think is incorrect. ??

What about these Detroit gaskets I see on E-bay. They seem reasonable except for the ridiculous $20 shipping charge...

Is there another source for these Detroit 4.125 bore gaskets? This is the only place I've seen these gaskets. Could this seller misrepresenting a set of P4120094 gaskets??



Cometic has them from .016 and up I believe.



Is the MP 4120094 actually a 4.125 bore instead of the 4.060 bore in the MP catalog?

70aarcuda measured a set he had at near 4.125. But I don't know how old they were.

Wonder if the current MP 4120094 is actually 4.125 and mis-labeled in the MP catalog?

The .028 compressed would be fine for me. And they are like $35-$40/pair.
