Porting question

[cb3016]

I don't want to buy a new O2 Housing, so i'm going to port mine, I ported my exhaust manifold about 6 months with a Milwaukee Die grinder (awesome tool for porting, u use a dremel it will take u a week, u use a Die Grinder it will take a couple of hours). dremel is still good for detailing the runners tho. anyways heres my question, anyone know where i can get some longer carbide bits? or an extention so i can reach the whole shaft? What other tool do u guys do when doing your own porting? just curious if theres something better I could use.

This place has some of the best prices i've seen and you can get just about any carbide bit made.
