    I am not sure I understand your question. I think the figures of 3.5 and 3.2 mm lift at TDC are for the purpose of degreeing the cams. I never found that very helpful, because there is a lot of deflection and tolerance involved in the actual lift that is translated to the valves. Plus there is the problem of accurately measuring exactly how much your valves are lifting. Like I said, it is very difficult to line up your dial indicator probe perfectly parrallel with valve movement. The cam gets in the way.

    I degreed my cams my carefully measuring degrees at initial opening and closing, then compared degrees at max lift with what Schrick recommends. Once I fiddled with it for a bit it was all right on.

    I used Turner adjustable cam gears to get things right on. As it turned out, both cams would have been absolutely dead on with non-adjustable stock gears anyway......sigh....=)
