On the fast road pistons 11.2:1 the valve cut outs are larger on the exhaust side where i thought they should be bigger on the inlet side due to larger valves ?
Anyone got a pic as its clear when you see them.

I have the same pistons and they can take up to 36mm valves (I have exactfigure in one of the emails from Wossner). Anyway, I have 34mm inlets and cams and it's fine. So there's nothing to worry about.

Yes, but don't forget to correct for magnetic declination or your engine might sieze!
