Pro comp SB aluminum heads ebay combos

This came up on a prior thread but no flow numbers were given. The only numbers I could find on the pro comps is from the EBAY seller mrperformanceparts:

Might as well post the numbers compared to Edelbrock (from their home page). I'll do it in the format of lift intake exhaust (Procomp/Edelbrock)

.1 73/62 63/52
.2 129/119 109/105
.3 190/175 143/142
.4 235/225 171/169
.5 251/251 184/185
.6 255/260 191/190

I'd like to see flow numbers from someone who's not selling them. Hopefully there will also be some dyno testing. Seems they are only available from a few Ebay sellers so far.

I try to buy US products but it seems Edelbrock needs a little competition.
