Explain how so???

They have stock casting numbers on them.

Ford's going to retool an entire casting line for 1 pair of heads for a show car?

I see that they had a great deal of hand porting, but everything else is indentical to stock (even the entire valvetrain)

Think what you want i have seen them and there was more that 1 set

just like they did about 10 heads High Port for the focus Zetec for the Mcguires car, you havent seen those eather does this mean they were not made

Ford does one off to one dozen, stuff all the time this is how they test new stuff

"Knowing that airflow is super critical for this little engine, Duttweiler ported the intake and exhaust ports as well as the four-valve combustion chambers. Both Duttweiler and Ford Motor Company engineers agree that short stroke motors don't like a lot of camshaft. Big lift and duration do not work. The gross valve lift is a mere 0.340 inch, but the pair of intake and exhaust valves per cylinder makes up the difference in ultra-high lift all across the entire rpm range. There's nothing else trick in the valvetrain. The valves are stainless steel factory units, and even the valve springs are stock."

I did not discuss the heads with him. This is what the article said...stock valves, valvetrain, cams, ported & Honed. Not sure if/why a different casting..these heads flow very well in flow bench..2.5 better than 3.0 despite smaller valves! There would be room for improvement with the 3L valves too, a must IMO. Tom, IIRC you had upgraded valvetrain??

I'm not critizing you efforts just reponding to your initial comment about out-running turbo V6s. Turbo is the best solution for zetec without a doubt.
