Engine goes... KNOCK!

The !@&#@(! thin Mopar head gaskets are on "national backorder", nobody I've called has any in stock. The engine guy thinks he knows of a source that may have them so he's gonna give that a try. If not I guess I'm back to the Fel-Pro's.

I use the mr gasket 1120s since they will fit a larger bore but not as big as the felpros 4.180,they are .028 compressed with a 4.140 bore,heres a link.http://store.summitracing.com/partdetail.asp?part=MRG-1121&autoview=sku

That's exactly what I ordered. I'm pretty sure they're the same as the Mopar gaskets (which aren't Mopar, there's another name stamped on them). Even the bore is the same. So the Mopars are 4.140 or the Mr. Gaskets are 4.060. I didn't measure them so I don't know for sure.
