What are your favorite 318 valve covers?

Tax return arrived so it's time to take care of all the little pesky problems on my dart. One of these problems is a set of leaky stamped pos valve covers.

So, what are your favorite valve covers? I've been leaning toward the cast MOPAR covers just because they are the easiest to find, but I have no idea as to how well they seal/prevent leaks. The engine is just a plain jane 318. Nothing special.

I already did a little searching on here and have decided on the mopar performance steel core gaskets. Now I just need to choose some good valve covers.
