All specifications (angle) referring to 1mm valve lift and 0mm valve clearance.

Notice: When installing the tuning-cam pay attention to the valve-to-piston clearances they should have a min. of 1.2mm at the intake valve at 10° before t.d.c and 1.7mm at the
 exhaust valve at 10° after t.d.c. (Minimum distance between piston and valves occurs at 10° before t.d.c (EV) and 10° after t.d.c (IV)).

 In the case the minimum clearances cannot be met, the valve pockets on the top of the piston have to be milled.
