I don't have the data, but compare your 2300 PVCR to the factory size. If same or slightly smaller I'd just try it out. If significantly smaller your WOT mixture may be lean enough to cause problems. Will you use an aftermarket plate with jets to replace the PVCR? The PV vacuum rating must be low enough that you can't reach it at any cruising speed, but will kick in whenever you need passing or acceleration, regardless of the number. This means that the PV will vary based on axle ratio and car weight, your driving style, etc.

As for jetting tips. I jet as necessary. Someone will disagree with me and want to start arguing with me and I really don't want to deal with it. But for starters, i would probably just throw 72 jets in the outboards and than jet as necessary. When I was running sixpacks, i may spend 5 hours laying black marks and making my neighbors crazy on a saturday.
