They are all with the symmetrical port head now. It simply makes more power under the new rules. AJ an other Mopar teams got caught with their pants down when the RPM limit came in. The symmetrical port stuff got put on the back burner as it was down on power to the asymmetric stuff under the old rules so development stopped on the symmetrical head. They are all playing catch up now. McGaha and team stayed with the symmetrical port stuff from the get go, the reason he ran so poor when in a Dodge. But that info paid off in sticking with it in the end. FWIW McGaha has a lot of irons in the fire with other toys he has. A friend runs his Engine Shop.
