I hear you loud and clear PB.
That is exactly why I gave 'em a try with the new type gaskets out in the market theses days to see if I could make 'em work. They do with a little bit of tightening and good Moroso blue gaskets. I do go in now and then to give 'em another half turn or so to keep things from loosening up and leaking.
I would also think that the new Superformance gaskets made/distributed by a fellow Moparts member here would work fairly well with the dreaded stamped covers.

PS: are those BEST MACHINE covers made by them or just a decal on a aftermarket custom cover?
I was just at their shop last month with my car to visit. They were surprised at me just driving in.
I was like Yo! ya'll built me a street engine for the street.LOL.
