Match this 500hp/500lb-ft Combo?

The Edelbrock heads will have to be ported. There’s just not enough port window flowing enough air IMO.

Totally agree with that based on what everyone says and writes about them. I'm not shy about getting dirty and porting the heads myself so the edelbrocks could work. (Yes I known I probably wont do as good a job as a professional or CNC ported head but diy is the fun part of this hobby for me.) The expense would be if there is a decent gain going to a 2.08 valve.
The pull for the TF heads is that they flow really well all over OOTB and I have heard the port shape is a little different than stock or RPM with a slightly higher floor and better short turn and might just be more efficient over all.
W2/W5 would be great, but those are rare, valve train is rare and expensive and most of them have been ported to the point they probably wouldnt work well for my target combo with a smaller cam and more low/mid torque than all out RPM HP goals. I think something flowing over 300cfm might be a bit lazy in a street car? (then again gen III Hemi's dont have any issues with +300 cfm heads on the 5.7)

Now as far as cam size goes, BP stuck in a small stick to make this thing produce torque very early and @ a 396 CID, it should be making a lot of it. This is huge street car fun. They (BP) chose a “Street” cam for this purpose. Not a huge lift cam so it can be easy on the springs for longevity and enough duration to make it a good driver with a mild stall converter and appropriate gear selection.

That long, fun street car 2500-5500 torque band is basically what I am going for with this combo. It seems like a lot of the chevy hydraulic rollers have the same similar specs to the .904 lifter lobes for mopars (or at least the ones listed by Comp and Hughes I have looked at), so I could get a flat hydraulic mopar cam with basically the same specs as that one BP has listed. Who has the best Mopar lobe selection?

It probably won’t peak at a high enough rpm with a cam in the low-230’s.

What duration would you suggest compared to the one BP has listed? It peaks around 6000 and torque isnt dropping off a cliff with just 230 intake. Wouldn't a 235 intake bump the hp peak up a few 100 RPM and probably get the hp over 500?
