Home port/polish Explorer U/L + GT-40 irons.

[Falcons Talon]

I finally scored a set of gt-40 irons off of a 94 cobra for a great price. I already have the Explorer intakes, and now I have to get started on some home porting and polishing. I do have a few questions.

First, I have an electic drill. Is this the kit that I want to use for the work port/polish bits, or should I get a dremel and a similar kit? If I get a dremel, is the 35,000 rpm variable speed the one I want or can I gat away with a single speed?

Second, Is there a definitive guide on home porting/polishing. I already did the search and found some info on cleaning out all the flashing, opening/smoothing out the exhaust port, gasket matching, and not polishing the intake runners because of turbulence needed...

Third, did anyone feel like they were about to "screw the pooch" when working on their first port/polish job? I've been putting it off because I'm a little afraid that I'll mess something up, but I don't trust anyone else to work on the stuff. I don't want to just bolt and go to have to come back later to squeeze evey last ounce out of it.

Thanks guys.
