    Everything looks great!

    .2mm sounds fine, my cams suggested .006/.008" or .15/.2 for int/exh. Excess clearance, meaning in the acceleration ramp causes things bang a bit. Too tight and the valves don't close fully would be the concern but many here have used CatCams with no reports of issues I've seem so I really thing it will be fine

    Thanks Mark. Your input is much appreciated. I will plan to adjust all clearances to fit the new cam spec.

    Best, Peter
