Just pulling your leg about the valves , and about the clutch I think I'll
just wait and see if it slips, if it does, I'll only have to pull the engine
out of the car what's that compared to the complete overhaul I just did !?

Extra clearance means that the cam is already well up its ramp so
when the valve train closes up the shock to it can damage things. I
hope you were just pulling my leg! The people who design cams
work pretty hard to design a smooth ramp to minimize valve train
shock. There are good reasons for this and it would be foolish to
ignore it. Besides, excess valve clearance is valve lift thrown away,
and that causes a loss of power.

If the clutch geometry is wrong then the pressure plate operating
levers may bottom out before the clutch releases once the driven
disk is worn just a bit. You can force this to work, but it requires
large forces on the cable, pedal assembly, operating arm and
throwout bearing, and this is hard on all of them. It is possible that
your machine shop corrected for the flywheel resurfacing and that
resurfacing the PP is responsible for the change.
