I did mine and i just matched it to the heads as best as possible and smoothed it out. it's hard to get way up in the curve of the runner but i just basically did the best i could and smoothed it out.

You will need to get some long rotary files (cutters) in tapered, straight, and flame tip. Use those to knock down all of the casting boogers (don't open the port to sewer pipe dimensions) and then use the cartridge rolls (you will need to get a long mandrel for these also) in 80gt, 120gt, and 240gt. Should get straight and tapered rolls also.
Have fun and go SLOW!
