Found a good way to clean carbon off pistons/what tools do I need to port?

Howdy,
I've been piddling in the shop downstairs working on the stock E7TE heads and I've been cleaning off carbon off of my old pistons (though I won't be using them, just wondering how to get it off best). Well, first off, how to get the carbon off easily :flag:

In my Dremel tool kit, I found a silver wire "wheel/brush" that came w/ it. I started using it on the old carbon-y pistons and it started working well. Just keep moving it and don't leave it there too long and you can't really even see any scratches this way. Warning however, the wire brush started "shedding." I felt stuff hitting my face, arms, etc and I just figured it was pieces of carbon. I looked and it was the little pieces of wire. I'm fine of course, it's just annoying to have all of these little wires stuck in your shirt and stuff :rlaugh: After the wire wheel retired itself, I then used 400grit sandpaper and cleaned the piston and it turned out well. I didn't clean the valve reliefs 'cause that wouldn've taken too long, but I'm sure it works well also. :)

Secondly,

What is a good kit to do port work? I've been working on the "exhaust bumps" on the E7 heads, and all the bits I have didn't do junk.

So one, what kind of drill or tool would have enough "torque" to work well, unlike my Dremel. Secondly what bits to use? I used some cheap $1.50 bits to debur my old 302 block (just for practice) and it seems well. So what kind of tools, bits, instructions do I need just to practice port on my old intake and old heads. :flag:

Where all should I try to dubur the block? I did some where the timing chain cover goes, oil pan goes, etc. but I was careful not to debur to much as to mess up the gasket surfaces :flag:

Thanks for your help and for putting up w/ all of these questions :nice:
