Wr426 valve clearance with YZ timing

My question; is the valve tolerances the same when the timing is changed to YZ timing? It looked advanced which seems like the cam lobes would be past their ...peak.

I am also wondering if this is possible without changing the cams. If they are changed what could they be and again what would the tolerance be?

Please help, winter riding could start right after this storm. (Not a powder day? must MOTO!!!)

Thank you.

valve clearance is the same regardless of cam timing.

Thank You!!
