OOTB EZ-1 - how far into the port does the Indy CNC go?

For an average guy, I think paying the $150 is a no-brainer. You get CNC matched bowls too. I can port heads, but I feel OK going in on iron heads....a set heads that a slip doesn't mean going back to teh boneyard - another ballgame for me

And, if I remember correctly, the OOTB EZ-1 flow wasn't too far of the EZ-295 version. I think a good bang for the buck would be some EZ-1's, and having you do a basic prep on them - ie touch up the valvejob.
