HP gains?

Yep, finally found them on my phone, Sir Rumble. The first column is heads as ported by my machinist, Doug Domhoff. Second column is after the new port job.
Have no flow info on the Super Victor other that it sure looks different than when i sent it to him.
Actually Doug's hand port job back in '19, beats the actual Trick Flow numbers. so he did a pretty darn good job for a Chevy guy. The new number are pretty good. I think.
