At .40 I would start to consider custom length push rods. Earl I've bought some rebuilt 906 heads that have had 2.14/1.81 valves installed and the head surface at least smoothed off, but I don't know if they have been milled very much. Where would one take a measurement to determine how much metal has been removed? I was thinking about milling these heads to increase the compression ratio, but didn't want to increase the valve train problems. I suppose .010 would cause very few problems.
