'72 Dart Custom

I was checking out the engine today to see if everything looked okay and I noticed one thing that wasn't. The MP valve covers don't quite clear the Performer intake. Anyone else have this problem? Would it be better to take material off the intake or covers?


And on a side note, would you run headers on a combo like mine? I was thinking of just using the stock manifolds. What kind of gain could I expect? Thanks!
