Right now I have just some plain jane stock heads on my 350, I have a comp cams XE268, air gap intake, 600cfm, and headers. I want to port my heads but I don't have the money to have it professionally done. I have an air compressor and I think I have the right tools but I have NO idea how to do it or where to start. ANY help would be MUCH appreciated.
Thanks.

For a simple pocket porting, you can do it at home just fine. Check out this link www.sa-motorsports.com/diyguide.shtm (http://www.sa-motorsports.com/diyguide.shtm) for some info.

One thing I do not aggree with in the head port guide si ginding the port to match the gaskets. You want to port match, not gasket match. The area around the intake gasket is the most efficient part of the port, making it bigger will just reduce velocity at that point. Only high flowing heads is this area any kind of restriction. Just use the gasket as a guide to match the ports, the gasket will usually be bigger, but that is not a problem. The top of the port is the most important to match, at the bottom leaving a step (head runner being lower) as much as 1/6" can help bottom-end power. This causes some turbulence an helps remix separated fuel.

123,
Before you start on your own heads, see if your local machine shop has a junk head, maybe a cracked one, that has been cleaned. Take it and do one cylinder completely. There are several good books out there that tell you what works best. Dave Vizard's book on Chevy heads is one of the better ones as far as porting goes. Once you have done one cylinder of the "junk" head, decide if you really want to spend the time doing a complete pair of heads. You are looking at at least a good 8 hours worth of work, most guys wish they had never started. Also, I have found that an electric die grinder works much better than an air powered one. You will need several different carbide bits at $40 each, a bunch of sanding rolls and some mandrels.
Makes paying someone to do it a lot more appealing !
Hope this helps,

Okay thanks alot, do you know how much it would cost to have it proffesionally done?

Billk has a good idea if for no other reason you can see how boring and time consuming it is. You must have alot more patience than I do if you can do a pair of heads.

Ask some local machine shops about doing a "pocket port" and three angle valve job for you.
Ask to see some heads that are done and have them show you what they did.
Then definately read the Visard books.
He's got a web page too. http://www.davidvizard.com/
