My attempt at speedmaster heads and moving the pushrod.

Well I didn’t know that you highly modified it to a square bore which should help. Hopefully you can flow test it as I think a Victor340, Super Victor, or Indy intake would suit your moved pushrod combo better. I’m assuming you are going with a 2.08 valve so flow numbers should be in the 330cfm area.

In other words, all you're doing is effectively losing the pushrod pinch altogether, correct?
Yes
