Default LIM porting tips

Now that LeSabre'* done with his LIM porting job i've picked up his old LIM and plan to do the same. I have a friend that is pretty handy with this kinda stuff, he makes pretty good money porting out throttle body'* for camaro'*, and i as just wondering if any one had any tips i could give him to make the process go along more smoothly.

Target width: .85"
Target height: 1.85"

Don't OVER PORT! Make your 3 corners the same radius as the head ports.
Smooth out the bumps and flaws, and don't POLISH anything. You're pretty much just taking the rough casting from the high spots down to the lows.

Your just trying to match them to the heads and yes, for the most part, you are 'fixing' them.
