Aftermarket cylinder heads?? Which is best for the money??

That's good because the HS rockers fit like crap on an Ede head... Bad if you want to run a rocker closer to stock spec.
I think the OP should run an iron J head :lol:
Why not a build similar to the RHS X head engine in the Blue 73 Duster? Looking for more than that one? Maybe a bit more compression and camshaft with a set of TF's. Either that or a well ported set of edes/copies.

As far as getting the engine in a good combo/chassis, the OP knows what he's doing!
Thanks Rob X4406 , I actually have a ad out looking for RhS heads but..I wonder how much difference the EQ heads are, this time i will have cal trac monos etc, when i did the other engine a super victor was recommended but i had a std victor. I would like to get another 40hp and have the rest of the car work this time.
