My engine dyno'd best with a ported 454r intake manifold, and the 2.0 bolts directly like a carb. I mentioned head porting because Dart heads respond well to minor porting. If you port match a good intake manifold, you either have to have it tapped for multiport, or go with a 2.0. Most of the shelf multiport kits are not going to come with a particularly good intake. They are designed to fit under most hoods. You have a raised hood and clearance for just about any intake manifold. An Edlebrock Victor Jr is around $300, a Profiler Sniper Jr is $385. Porting of either is around $400. I mentioned these two as they are potentially good candidates for a 540.
Let's say you have a BBC 540 crate motor with 650hp. If you make a few tweaks, it can easily make 800. Port match the heads with a good intake, and get somebody like Chris Straub to do your cam and you are there. Yes hydraulic roller, smooth idle in traffic, etc. Top it off with efi and your set. Im getting jealous just thinking about it, lol.
