I'm with you Nick,
My heads are stock unported vortecs. Everone I talked to said that it was likely that I'd do more harm than good by trying to port them myself. All I did was match them to the intake ports.
As far as modding the intake goes, I have a welder up here that does an absolutley awesome job raising the ports. We've had a few done now, perfect results. I bet no one would even notice that it had been done if you didn't tell them.
I can have the intake welded up and the surface planed straight for about 200 usd+ shipping. You still would have to port out the intake to match the heads though. Easy to do, or I could do it for ya for a little extra $.
The nice thing about that is that you only use one gasket, no spacers to mess with, bolts on just like the factory meant it to.
HTH
