I'd watch out for BB M/T valve covers. We had them on our superbird when we first bought it. Kept having valve cover leaks. Seven sets of gaskets, cork, rubber, etc... Still leaks. :finga:
Went to 1st Mopar nats and talked to some folks, they all said to pitch the M/T valve covers as they are junk. We bought a set of stamped steel chrome ones, and they sealed first time. :cheers:
