Randy, which ring blew out? Wondering if it's the same one that most have. That passenger side rear cylinder?
Felpro makes a Permatorque version of their standard 3.8 composite gasket which is a direct application for our car.
Felpro also makes a Permatorque MLS gasket that is an application for the Ford 1/2 ton with the 4.2l motor in it. I belive 99+. This gasket will work just fine in our block but is not part of it's application. No MLS gasket has a application in our block. We're just steeling from other applications.
As far as copper, you never want copper unless it is a full on straight out the door race car. Copper headgaksets leak on engine cool down and it get's a tad irritating. Really not ment for a street car.
Gauge the head gaskets you get based on what you intend to achieve with the car. If you don't have any goals go take it over 300-325rwhp, the standard head gaskets with ARP bolts and a good engine tune should do just fine.
