On those cylinder heads, most aftermarket rocker arms have a clearance issue at their trunnions due to the valve placement, meaning that the trunnions to the adjacent rocker arms touch each other. With those aftermarket rocker arms, the simple fix is to grind the trunnions down for clearance--welcome to the world of custom engine building. I do not know whether the Miller rockers need clearancing or not...but if they need to be clearanced then simply clearance them as you would all the other brands.
