AFR has moved their rocker studs and valves several times. This is why we're on V2 of their heads. AFR is not going to make their heads based on available rocker arms. That's just silly. There are a lot of factors that go into where a rocker stud goes, especially with canted valves. It's not just arbitrary. One major problem is the pushrod side of the rocker and it's proximity to the valve cover. Not very much wiggle room there at all so you can't just decide to move the rocker away from the valve without causing other problems. The easiest solution is what I did and that's to come up with a rocker that fits the application. When you're trying to do things with a cylinder head that it was never designed to do, you run into these things.
