I ordered Mopar performance head gaskets part number P4120093. Advertised as having a bore of 4.06 and compressed thickness of 0.04 - what I got are Fel pro 8553PT gaskets in a Mopar box! These have a bore closer to 4.2 and a compressed thickness of about 0.05 - no better than what came in my full gasket set. I will be sending them back. Just wanted to make sure nobody else made the same mistake.
 
I have just oredered a set of P4120094 gaskets which are supposed to be .024 to .028 compressed thickness and 4.06 bore. We'll see when I get them. I'll let you know.
 
I missed something here. wildbill, where did you order the gaskets from. I am looking to get something similar and don't want to make the same mistake. Thanks, Dennis
 
They were ordered from Summit. I think that Mopar performance is just relabeling the Fel pro gaskets and selling them as their own. Unless somebody returned a set of Fel pros to Summit and they accidentally resold them to me?
