STOP - Do NOT bother doing the clearances now

You should redo them AFTER the rebuild, as new head gasket & retorquing the head may well lead to minor distortion & effect the clearance measurement!. ALSO, the clearances are best re-checked with the lobe pointing 180 degrees away from the shim surface - in line with the axis of the valve stems.
