I assume you're wanting a 24 degree head. I think I would try the Dart 370 Ovals, those make real good power on a 540. I was just reading about Artis Houston's motor that he has for sale, the ones that used to go 8.18 on 275 drag radials with a 548. They might be spinning it a bit tighter than what you might want to and using more spray. I did read that they said the Dart's were untouched on that motor and it made 1000hp on motor alone which sounds pretty healthy for a 540.

Other ones would be the AFR 357's or the Canfields or Profiler's with some porting work done.
