I would run 24s at least and maybe even 30s. Are you pistons notched to clear the 2.02 Edel valves, or do you have different pistons?

24's are plenty (www.pro-flow.com -- select meter sizing and scroll down for info on HP vs. injector size). You're probably right on the edge with 19's. Who ported your lower/upper? Unless they really know what they're doing, you may be limiting your whole combo with that intake.
Investing $60 bucks in a wide band dyno run would tell you how your stock 19's are doing keeping up the with the engine's fuel needs. I'd invest in that before I put the money into maf and injectors.

^^ He's smart 
if you get an RPM intake or soemthing else good aftermarket, i would say 30s. normally that might be a bit big, but your also spraying on it too. Better safe than sorry.

His spray is a wet system - supplies the extra fuel separate from the injector. If he were spraying with a dry system, I'd agree with the need for 30's. But with wet, it's extra size that doesn't benefit in any way.

Your using big money Alum heads with a stock upper and lower. Ported or not, the stock upper and lower suck balls

Ported properly, the stock intake can flow comparably with the Cobra/GT40/Explorer intakes. If it was a good port job, it can work just fine with his combo; and he makes his big stuff with the juice - when you 'pour' the power in with nitrous, the intake isn't nearly so much of an issue.
thanks guys i ported the upper to match the gaskets between the plenum, and matched the lower to my heads they were ported intake side only on a flow becnh, i notched out the the reliefs on the stock pistons myself. intake is goin first money i have, but i think i should get the 24's. thanks guys

Sounds like your intake was 'port matched', not ported. I'd do the intake first - what you have there sounds like it's a big bottle neck to flow.
