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.[/QUOTE]

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
