Ignition module - why? I didn't see any mention of a performace module. They work or they don't. I would think a quality coil upgrade is more useful.
The dual snorkel is nice if you have it. Engine air is hot. Firebirds can use the turbo hood & get the operating vent setup - even better. When you are trying to squeeze blood from a stone, might as well squeeze everything you can out of it.
I'm not sure the carb cleaner will do much for a daily driver. One that I have seen work is old school: the old hand over the carb (in a choking manner) & give it throttle to pull the **** out of all the passages. I've seen that work for older Qjets.
A good old Performer EGR manifold should help. I wouldn't do a cam w/o a manifold too. And some roller rockers. New cam should bring new valve springs to the game too, and stem seals. Better heads would be nice too. I see those 305 world heads for sale a lot. There used to be a great carb guy in Trenton, I forget his name. Airflow Carbs, maybe.
Electric fans are a good bet for cars with clutch fan setups. Use a lower temp switch, tstat & get a hypertech to correct for it. (edit: I am out of the loop on chips-sounds like guys around here can burn them now too)
Some of that stuff sounds like a dealer hit list - check battery & alternator? Plus other non-engine stuff on the list. Stay focused. That sounds more like a winterization check.
I was so happy my LU5 305 blew up 3 weeks after I bought it!
