If you don't have the time - don't bother as a good DIY porting job - it's about 8-14 HOURS of work

Burs - McMaster Carr have a good selection. http://www.mcmaster.com/#carbide-burs/=2xfuir

The one thing I do have to say here and it was mentioned above is that unless you have a flow bench, I would just port match the intake to the heads as well as the exhaust ports to your manifolds plus smooth of any obvious casting boogers. . Beyond this, you could be doing more harm to your air flow then help - then of course is the potential of "falling through" to a water or EGR port. You also need a good 3 angle valve job AFTER your port job to finish it up.

Here's a pretty good article for a DIY porting job: http://www.pirate4x4.com/tech/billav...0Abrasives.pdf
