My repop RAIV actually has a decent amount of meat at the top. Probably enough to get by without welding for a mild port job and raising the roof a pinch.
I had to clean up the original HO piece on the 455 I built a couple years ago, and those were on a set of Dan Barton ported 7F6 heads that flowed 285 cfm. The port match was off to begin with but wasn't bad when I was done.

just saying what dave has posted on his website now for information purposes. for his intake porting service he wont do the repro RA & HO intakes.
