Mopar Performance Valve Cover owners!!!!

I'm looking to put a new set of Mopar performance valve covers on my 318 with stock intake and LA heads.
I have read about the Mopar Perf vlve covers not seating correctly. Anyone have any experiences with this issue?

I have these valve covers on my 318 with LA heads and a eddy RPM. I had to grind some of the lip on the intake side because the lip rested on the intake before the head. I understand that that is what happens with most. Perhaps someone with stock intake will chime in.
