Aluminum Heads

I am on kind of a smaller budget for the heads, so i cant get the trick flows..so, out of the Edelbrock E-street 84cc, the stealths, or promaxx, which would give the most improved power over the bone stock 452's? Keep in mind, i will be using the new aluminum heads out of the box with the ports they come with..no extra porting..Looking for the most power per money spent in this price range of these heads.. The engine is a .030 over 440 with the 2.061 compression height TRW 2355 pistons that are currently in it, Holley street dominator intake with a race modded thermoquad, 1 7/8 fenderwell headers, 3000 stall, and a MP 284/484 cam installed 4 degrees advanced..Keep in mind, i am willing to change the cam also for something better if it is recommended also..This is in a 1972 dart swinger. It will mostly be a fun car but i do want the most i can get out of it with a cam and head swap as i may do a little drag racing with it every now and then and dont want to be embarrassed by the little 4 bangers..
