Valve Cover Gasket Question (yes, another)

What brand of valve covers are you using???

When we installed the cast aluminum valve covers (I believe they were the M/T covers) they leaked... We installed 7 different types of gaskets on them including the fel-pro neoprene ones and they still leaked...

We talked to some others at the Mpoar Nationals that weekend and they told us that those valve covers are junk... We changed to a different brand and they sealed first time...

Krazykuda -
See below. The 'Mopar' cover is the one that was on the car and failed twice. I purchased the chrome stamped cover because I've heard before that the cast aluminum are problems.
To be 'safe' (?) I'm going to use the stamped cover instead of the flashy Mopar cover.
I'll gentle use sealer between the gasket and cover.
The concensus seems to be to NOT use sealer between the gasket and head surface (even though that is where it leaks) so I won't use sealer there.
If it works then I'll switch out the drivers side cover also.

I'll let you all know how it turns out!
Thanks again.
