Ported Magnum Heads, Pushrod Pinch Removed

ship one to Mr PRH, I'll pay for the return shipping if he'll flow them.

I’d be fine with that.
But I have to believe there’s a flow bench within a reasonable drive from Columbus, Oh.

What intake manifold is that?

I have basically zero experience with stock magnum heads.
What would be considered pretty good numbers out of some porting on oe magnum heads where the pinch was still there?
