They had to machine the head down where the single stand sits and clearance the rails for the rockers. I still had to hand grind some for the rockers at the rails. Another problem I realize now is that the raised rails are a mistake with the Jessel rockers. When you use a spacer rail to raise the valvecovers you can set them on the head and see + mark where to grind them. With the raised rail and set the valve cover on you can't see where they are hitting and how much to grind off. If I can find somewhere local I'm going to take my rails down to stock height.

When you cut the rails down, it helps if you angle mill the head on top. It angles the valvecover away from the backside of the rockers. If you do this, you need to plug the original valve cover bolts and re-drill when your set up on the angle.
