Leave the intake ports finished with 80 grit, but polish the exhaust ports. You can get all the necessary tools from mcmaster carr (mcmaster.com).

If I recall, I bought:
1/4" shaft 6" long 3/8" round carbide burr
1/4" shaft 6" long 5/16" flame shape carbide burr
1/4" shaft 6" long to 1/8" cartridge roll arbor
varying cartridge rolls in all shapes and sizes and tapers from 40 grit to 400 grit.

Here's how mine came out. Sadly no pics after milling and cleaning up the heads.

i cant understand the people on this board saying not to PP your own heads. as long as you don't go crazy and follow the good homeporting pics on this board your fine. this guy did a great job and according to the info on this board at least picked up 15 solid hp. i would be able to add my results but TTP closed down here in jersey so i lost my baseline comparison. maybe ill go to the strip tonight untuned...
