MSC industrial supply sells some nice carbide bits from the smallest to a 5/8x1".
A cut above distrubuting carries a decent selection also. Good place for cartridge rolls and flap wheels.
Dont have links but sure they will show up of you Google them.

yeah all i used was a dremel and a few tips....took a while but it worked..oh also a drill with a rough cutting bit to get a lot of aluminum out faster. i just got a used 60grit flapper wheel from a friend and i used it on this one side of the pics i took. thats how i got it so nice and clean lookin. it worked good but the wheel is ablout out...i need to find more but i have had no luck in town findin any. i was thinkin if a got like 10 or so and a extenstion i might be able to get them down in there more...but i think i would go through them fast that way.....anyone else have any ideas? if i could find an flexable ext to get down in there that would be cool but not sure if it would work to well

Goodson Tools is a great resource for honing tools. The ball hones work great. It makes the job less tedious and you get professional looking results. Additionally the ball shape keeps the ports round and not deformed (which is easy to have happen when doing it freehand). I did a killer job on my super ram with the hone *****.

Check the ***** with this link.

The link below shows all of different sizes and grits

I was able to remove all of the rough casting plus more with the ball hone. The ball hones come in different grits, so I started out with a course ball and then did a final smooth with a finer ball. I kept tabs on the runner sizes with a digital caliper. All that you need is a power-drill and some cutting lube.
