To actually verify fuel distribution on any induction system you would need thermalcouples on each exhaust tube to monitor temperatures. Visually checking the spark plugs could only detect gross distribution problems. Some say they can do this with an hand held IR gun - I'm not a believer of that either.
How you going to use an IR gun? You cold idle, but that's it. Underway -where it matters, ain't gonna work.

Well if you don't need to smog it to register and license it then the sky is the limit. Start with basic foundation builders like headers, free flowing exhaust and a good intake like the Renegade. I don't think the savings in porting your stock manifold justifies the effort when there is a quality piece on the vendors self for a reasonable price. Once you have the car running well with a good intake and exhaust then you can make internal motor improvements one at a time so you can sort things out as you go. Unless you have a lot of sbc experience and with CFI then have at it but if you did have a lot of experience you probably won't be here asking for advice. Making changes one at time allows you to keep track of the effects - good or bad - and recover from mistakes if needed.
Good luck.

listen to ^this guy giving CFI advice....and he doesn't have one! I especially like the part about the value of porting the intake. Cardo....you know what a WELL ported CFI intake is worth in the 1/4 mile? I do. You know how much it costs to port a CFI intake? I do.

All I'm saying is that my '84 CFI has surprised a few people, and I'm sure I don't have all the right answers.

I went with a mild cam, renegade, 1.65 rockers, heads, full smog stuff delete, and melrose exhaust system.

I know this is almost a decade old, But an LT-1 exhaust will bolt right in to a Crossfire equipped corvette? Im trying to find a budget option for my old, and rotted out exhaust.
