You didn't give much detail. Is your material cast iron or aluminum? For what application (GEN1, GEN2-4)?
In other words, did your re-create the iron head form-factor in a different material but with higher flow in mind?

and whats the cost of these CNC irons?

It's not hard to outflow Falconer. They removed the intake vane that split the air around the valve stem, a big no-no. If you look at the opposite wall of the vane, there is a crevice to compensate for that vane that helps direct the air back down towards the combustion chamber.[This message has been edited by lou_dias (edited 04-27-2013).]

Nice that you got good results. I believe I'm using the same throttle body on my Trueleo intake now but even with the stock bored throttle body on a Mustang dyno I did 187/249. However you are enjoying the power past 4500 RPM that I couldn't reach due to the intake neck.  ...a problem I have since rectified. I believe I spent $1450 on my heads and well worth every penny. It seems you went close to the extreme as my machinist but he did leave the vane.
Here's yours:
Here's mine:
Yet another example of iron heads putting down 240+ lbs*ft ... who would have thunk it?

you only picked up ~30 CFM on the intake with CNC porting? after bowl work and minor port work, my irons flowed what yours do, with little variation between ports.
