Comp 42-224-4 cam .520 .523 dur .050 230in 236 ex
Comp 825-16 lifters
Comp roller rockers

Arp bolts

Lots of carbs will perform similarly. It's really up to what you can tune, or have tuned, well and properly maintained. Your build is not wild, so you can grab pretty much any 650 - 850 carb you want.

QJet has the bad rap because it's a relatively complicated carb. Set it up wrong and it's terrible. Set it up right and it's great. Getting good cores can be a problem.
Holleys are all over the place and you can get parts off the shelf at the local parts store.
The new Street Demons look really interesting. Should be between the Edelbrock and Holley in complexity, but get street manners closer to a QJet.
I'd say skip the Edelbrock carbs, but they're good for just getting an engine running, and are easy for a novice to tune. It took lots of compromises to get there.

You said pro touring. One separate consideration is if the carb will be on display. If so, then your taste in appearance may be a factor. The good QJet shops can replate the carbs so they have the nice yellow-ish shine. The new stuff is always available in multiple finishes.

In the end I strongly urge folks to go with a carb that either they have experience tuning, or have a good friend that can tune well. Proper carb tuning is very important. "Out of the box" is almost always BS.

Quick Fuel Super Street 850, which is really about 880.
