Any info or flow data for a set of stock C9AE 429 Boss heads versus a modified set of C9AE Boss heads from the old "Gap & Roush" racing program. This must have been prior to and before the A441 stuff came out ? Was it used in Prostock of some sort. Just looking for some general information or history.

Thanks Mark

A few flow sheets here... http://users.erols.com/srweiss/tablehdc.htm#Ford

Yes the stuff was used in the 70's mostly, some of it may have lingered into the 80's but by the mid 80's the A441 stuff was the hot ticket.

You'll also see alot of NACSAR stuff from 69-70ish around too.
