You remove the double throttle plates (obviuosly) and then take a die grinder with a decent burr on it and start grindin away the excess metal, and sharpen the middle into a spike
I take the center down below the hole where the double throttle shaft went through and then start sharpening the sides.
End result should be somthing like this
the sides are not bulky like the picture looks, what you are seeing is the shiny, polished surface where i took the metal away.. I need to do another one and get a "head-on" pic so you can see it better

Street porting and throttle body porting are two completely different things.
To street port, you must disassemble the engine, port it, then rebuild it.
The throttle body porting is easier, but there is some debate as to whether there are actual gains on an otherwise stock car. I believe that there are many throttle body porting threads, and there may even be one in the archives. A search for "throttle body port" shoudl turn it all up.

If you're really serious, we should take this to PM. But basically, we're talking at least $1000 in parts, no warranty past "Yes, it will start up" and several months (I'm very busy). Labour to be determined after the core is pulled apart. Honestly, it's not worth pulling apart a perfectly good engine to street port it. The power vs. cost value is just not there.
porting really isnt that bad, as long as you have a template, and then tape off the rest of the surface incase you slip you dont mess up the surface. I used a dremel, and one of the dremel metal cutting bits. Worked out great. But next time im going to use nice carbide bits, to cut in deeper. I was only able to open the hole with the dremel bit.
