I'm rebuilding a 1952 88 Dominator cylinder head for my project. I replaced the rocker shafts on the lefthand intake, exhaust, and right hand exhaust valves with no issue. I froze the rocker shafts and heated the head with my torch. They fell into place smoothly, so I was shocked to find that the rocker shaft for the right hand intake wouldn't fit in the head, even with the heating and cooling treatments. I measured the rocker shaft to be .4975" in diameter. I don't think that the aluminum is concentric as I measured it to be 0.498" in one orientation, and 0.4965 in another. Any tips on how to proceed? Thanks in advance,
