Couple of Questions

RE: Couple of Questions
I have a crate 302, and I do believe they are stock headers. By bogs down, I mean that I will be driving normally, not accelerating at say 30 mph. If i floor it, it sounds like too much fuel is getting into the engine and it is getting choked up. The engine almost dies and starts to sputter. After about 3 seconds of that, it will pick up again. Same thing happens at idol. It's pretty annoying.

IMHO the first thing you should purchase is a Factory Shop Manual it provides all the details of the things you need to do to the car to keep it and you happy. However, you have a modified car, e.g. the carb and heads, so you should also get a good book on the 289/302 engines.
Spend your money on the basics and getting the car to run correctly BEFORE going for performance!!! I always begin my relationship with a "new" used car with a complete tune up (plugs, points, dist. cap and wires, set dwell and timing), spray cleaning of carb, replace all filters and fluids. etc. This will establish a baseline for future mods.
Since you sound like a novice (not a slam, we all started that way) a couple of hints about the spark plugs. Change them one at a time, that way you do not get the wrong wires on the plugs. Verify the gap is correct before installing, I believe 0.035" for a stock ignition system. The place you buy the plugs will be happy to sell you a gauge for this (pretty cheap). While there buy a short piece of heater hose that fits snuggly over the ceramic part of the plug. Use this to start the plug into the head several turns before "seating" the plugs with the spark plug socket. Put antisieze on the plug threads, really helps next time you go to remove them.
Since you already have a larger than stock carb (yours is 600 CFM, stock was about 480 CFM) and better flowing heads you will get good benefit from headers. However, I would be really suprised if you can install GT 40 heads with a stock exhaust manifold. What do yours look like, massive cast iron parts or tubes?
I would stay with the stock shifter for now, are you having problems with it?
What kind of ignition do you have on the car? Stock? Electronic???
