No they may not flow as well, but the availability of parts that work with the track 1 heads is better than the sb2's

come on 7600, every dirt tracker knows small blocks don't make any power until they get over 8

were them sb2 heads new castings or ones you rebuilt, i've been looking at a set of them or some track 1 brodix's with some port work i'm going to be running the opposite, a 377 for a little more rpm in a blazer for mud drags, plus the 377 seems to hit a little harder

They were used heads from Hendricks , off of a cup car. I don't think you will get track1's to flow over 400 cfm , like these do .
