porting and shaving heads

22,1 msv sounds high? I'm only got around 15 msv when i calculated my
stock -00 heads in this software, what am i doing wrong?

Torq soft always measured squish velocity lower than other softwares and lower than my TSR. I think its the way the torqsoft software is written or setup equation wise internally. Don't worry about it. I trust my TSR that's based off of Gordon P Blairs findings, etc.

Ok thanks! Going to send my -99 heads out for machining soon so it's alot
of calc. going on now... Think i gonna aim at 13:1 cr. along with my
ported -00. That should be ok with our non alchohol (yet) premium fuel.
