Help me optimize my build

I see where you're going, and in the future I will build a motor better suited for what I want to do. However, I'm currently just trying to get the most out of what I have. Heads would be GREAT, but they're just not in the budget to get done before spring. I would consider some minor porting, but at this point I'm not comfortable enough to experiment on my heads.

Well if you know the size of the valves in your heads that would be awesome, because if they are small, it might be worth it opening them up, to a larger size. (ie. 1.77X1.5 to 1.88X1.6)

If you have the small valves in your heads, the carb you have is OK. But a holley would be better. However if you have the larger valves, you will benefit by going to a larger carb. And as you said the inexpensive 3310 Holley would be great. If you were going to go with a double pumper and put a couple hundred into it, you would do better by getting someone to port your heads and put that money there.

The camshaft you have selected does not sound like such a bad choice, But I am no expert at camshafts.
