High CFM heads - What would you chose?

Well then let me ask you the question on what not to do when I attempt to port heads. What would your #1 and work in thing be on that list?

Sorry guys, got back from work and the world went FUBAR on me.
Port numbers later...


I’m dragging azz from this heat but if you are asking out number one thing to do and number one not to do is I try to avoid major floor work as it limits my shaping of the short turn. Number one thing I do is widen the shortside and shape it according to where it sends the air into the cylinder. Aim the air away from the cylinder wall and towards the center of the cylinder. I hope that came out right.
