i'd say something like these, although u could probably get them cheaper at lowe's or homedepot. have u already got a die grinder or dremel tool?

I am going to use the die grinder for the most part and my dremmel for the more intracit areas.
And also should i get carbide ones b/c i hear they last longer?

Don't get anything but carbide..

I bought several different assortment sets on eBay, cheapest way to go. You should get at least a tree, a round and a straight with a rounded end. I stay away from the ones that have a square end, they leave too many gouges to feather out. 1/4" shank with a 3/8" outside diameter. Pick up a set of long shanks to port the intake track on the irons.

You will also want some stones and sanding rolls for finish smoothing. I bought stones local and an assortment of sanding rolls from McMaster-Carr.

yes, only carbide. preferably double cut.

Good point, I forgot about the double cut. Supposedly single cut works better on aluminum and softer metals, but I have found the they load up wprse than the double cut, especially with al. One trick I learned is to use a lubricant when porting, W-D 40 or P B Blaster. This helps prevent loading of the burs and makes cleaning them out easier, also gives a better cut. When they do load up, I take them to the bench grinder and clean them out with the wire wheel. As soon as they start to load, clean them, the more crap they hold, the harder it is to clean them out. Aluminum is the worst for loading up.

For intake porting, I prefer a variety of double-cut olives for the bulk of the work, including a medium size olive with a long shank. Plus, a tree and a small round. For the next step, plenty of cartrige rolls on both a long and short shank. And, finally, a flapper with three grits of sand paper strips.

The results are something like this...

In Tampa on Adamo and 301 is Wholesale Tool. They have a good selection and prices. Dont do the ebay, I have never seen a good quality carbide bit there.

Racing Beat has samples of what you should look for on their site.
