Something else I ran into - called B3 or whatever the relocation guy is, and found out you need to do that before you torque the heads down because you have to clearance the pushrod holes. I had already installed mine so I just went with it. He didn't seem put out by it, either from a usability or wasting time with a looky-loo standpoint. We were on the phone for probably 10-15 minutes. Seemed like a good guy. Also, he advised 0.030 clearance between the spring and rocker, so I used a piece of welding wire as a go/no-go gauge
