You'd spend a good chunk of cash buying and reworking some clapped out old 286 heads to get them even be close in flow to some mildly reworked 088 BBC heads.

If they’re allowed to run rectangle port heads, there are plenty of good ones to pick from.

If I could be around 700 I would be happy. We can run a vac pump also to help squeeze the most out of it as possible. Rules state the engine must match the truck. I already have the chassis done so I’m stuck with Mopar powered which I would prefer anyways. I could step up to the pro stock class that allows aluminum heads and 485ci. My buddy runs a ford in that class with kaase p51s that makes 950 and is getting the new sr71s next year. They really limit the Mopar heads in that class as well. No b1s. So victors or indys would be the better choices for it. If your buddy is making 950 then you would have your work cut out for you to match that with a 485 inch Mopar. You would need an aftermarket block (good luck there) as well as a really good set of Indy heads. Maybe the full on -1 heads or step up to the 572 heads. I'm not positive which would be the best way to go to hit 950 hp at 485 cubes but you can figure that out in a few phone calls. It wouldn't be a cheap engine that is for sure. Probably start at $20,000 and go up from there. Dry sump, belt drive, big cam, big springs, super high quality valve train, etc.

Any good head porter that you pick can easily get 320 plus cfm out of a W2 Head with 2.08 valves. Put a big enough cam in it to use that cfm with a nicely ported W2 Victor intake and go have some fun.

The 485 is in a different class so I won’t have to worry about it. Nope all trucks need to weigh 6,200 with the driver in it. No more No more or no less?

So they need to weigh the same, as close to 6200 as possible. The big block is heavier where you want the weight. There's a cubic inch penalty of 40 inches with a small block and no breaks or advantage for running one.
Either I'm missing something or the question is why would you even consider a small block when the heaviest 472 big block you can find sounds like the best combo?
If the results don't match the theory, change the theory.

The weight of the motor doesn’t really matter. If you are running a lighter motor, it just allows you to add more weight to the weight bar at the very front of the truck. You’re still working within the 6200lb max limit. As for any advantage for the SB....... Most of the rigs need wheel speed, so they turn a lot of rpm. The OP is looking for 8000-8500 capability. At those kinds of rpm, I think a 434 built around a Ritter block would have better reliability than a 472 built around a stock 400 block.

Correct. Even tho the big block is heavier on the front it still isn’t as far forward as we would like to have it. Getting the weight concentrated as far forward as possible helps use the mechanical advantage. Wheel speed is very important in truck pulling. Normally around 33-34mph is how fast the tires turn and the actual truck will do 27-30 pulling the sled with the slippage from the tires. Are max effort w2s capable of supporting 434 inches at 8,500?
