Re: AFD releases new head
I did the test a few months ago, and there is a lot of variables in doing the test. I can't remember exactly now, but the only way i could get close to 1.9 inches was if i used a very large radius for the corners in the calculation. I have the heads off in my room, so i can check and give port dimentions if you know how to acuratly equate it. I did the checks in the port approx at the pushrod hump area. This has been an ongoing debate with many coming up with a lot larger than advertized, but i wont say for sure as i am not an expert on the topic.
