906 head capabilities?

I’ve been working on my Dart for far too long now and when it’s almost time to finish it I’m having engine problems. I believe most of the issue is these knock off procomp heads. On the last start up an unfortunate series of events led to a bent valve. Can I get away with running 906 heads? The only concern I have is with my cam. The block is a 400 stroked to a 470, zero deck and the cam card is below. Thanks!

You better do some research and make sure what head you are running. Are they proComp or Speedmaster heads. Reason I ask is Speedmasters only big block head is an Edelbrock Victor copy with big offset rockers. You would not want to run those heads on that engine.
