Randy,
are these the heads ?

looks like a fair shake between the ford chev mopar. However, how fast do we want to go? an example... SS/H 327/299 4 speed car is roughly 336 cu.in at 3020 give or take a few, (at 336 in and a 9 lb break thats 3024, a good example) and they are running high nines and low tens on a good day. has basically the same shortblock we are talking here, (supermod) how fast will it go with these brodix heads, generally available manifold, and 750 holley? Same full bodied back half car, perfect for the class. add a fiberglass hood w/ scoop and there you go..
maybe it will go too fast for the older guys, below 9.99 its neckbrace, gloves, comp license etc. I'd support a cam max lift rule at around .550 to .575 to keep the expense and maintenance down and keep the cars in the 10's
