Why are you taking the heads off to do a cam swap? Are you having them machined? If not, all you need is an adapter for your air compressor that you can pick up at Autozone that keeps enough air pressure in your cylinders to keep the valves from dropping while you are changin springs.
Go ahead and put on an aluminum intake as well.

I know you already have them, but I wouldn't use K-motion springs. Every time someone mentions them it's a story about how one broke and dropped a valve and now they need a new motor....

I would still go with a set of Comp Cams springs, but those will do if you're on a tight budget.

Are those 25.95 a spring or for the whole set?
If so, 258 bucks all together for valve springs. 
For a mild 305 thats a little extreme.

Don't forget to either pin or machine/add screw-in rocker studs. I've pinned them in car after they started to pull, no fun. . .

What is pinning a stud? I had screw ins put in when I had my heads done, but what is pinning? Always want to learn something new... and something that may save a few bucks is even better....

It's a cheap trick, but for the little amount of money it costs to get screw in studs, it's not worth the hassle.

A hole (3/32" or 1/8", I forget), is then drilled from the intake side of the head through the stud boss and through the stud. The fixture is used to locate the hole, guide the drill bit, and control the depth of the hole.
Remove the fixture and drive in a roll pin. Move onto the next stud. For a low buck medium performance engine it is easily cheaper and easier to do then screw in studs.

Here's the .pdf file that Vader posted on how to replace rocker studs. Rocker Stud Replacement
BTW, here's the pin kit..... http://www.jegs.com/cgi-bin/ncommerc...23&prmenbr=361
and here's the stud kit..... http://www.jegs.com/cgi-bin/ncommerc...66&prmenbr=361
It's ~$30 more for screw in studs.
