My 440 is almost exactly the same as the OP's. The only differences are the cam (Engle .534 lift, 238@.050") and intake (Performer RPM).
Right now I'm leaning towards either the E Streets or the Pro Maxx heads as the best bang for the buck heads to replace my bone stock 452s. This might be blasphemy but I've been hearing that the casting quality and flow numbers are actually better with the Pro Maxx heads than the Edelbrocks.
I also read that but there was no way in hell i was going to ask about it. Are you also running the 2355 pistons or just pistons with the same compression height?
I'm running the 2355 pistons. I'm also running Hooker 1 and 7/8" Comp headers that are made for heads with straight plugs (E Streets, Stealth) but from what I understand can be made to work with angled plug heads (RPMs, Pro Maxx) by dinging a couple tubes. I bough them used and the #2 tube is already dinged so someone may have run them on heads with angled plugs already.
