Does anyone have any info on either head? Looking for the best head for torque and power from idle to 5500 smile.gif

FWIW, the Brodix site shows the RRB-0 flows 335/211 @ .600 lift, the new AFR catalog shows the AFR 265cc heads flow 332/272 at the same lift, both 28"hg. AFR aso outperformed the Brodix at low lifts as well. @ 400" Brodix 274/164, AFR 297/219.

For a little more info, the AFR head will not be available before the end of the year at best.

The advertised numbers for the Brodix head are without the CNC chamber option & this improves the low & mid lift numbers dramatically,,, at least on the small block ones. I have not had the opportunity to test the BB RaceRites yet.

Also, if you are interested in either head email me & I can probably save you a few dollars ;)

and the protopline iron head flows 348/248 at .600 lift

oops my mistake thats 380 /248 out of the boxand they cost less also

copo69 THe protopline head has a 320cc intake port so how can you compare that to a 265cc or 290cc port. Plus most of there heads dont flow what they say they do.
