I've only measured the vertical ones so far but openers are 0.00" with the shims turning but feel like they're binding and for the closers In= 0.0035" and Ex= 0.008". So both closers gaps are massive if the openers gaps are 0.00 as there's no adjustment to the measurements.

Unless carbon/crud buildup under valve seats then as things wear the openers get tighter and closers looser.
Set the closers as tight as you can without binding. IIRC original specs were 0.03 - 0.05mm closers and 0.10 - 0.12mm intake and 0.12 - 0.15mm exhaust openers, personally I wouldn't go any bigger than 0.12 even on exhaust.
They later 'relaxed' the tolerances to reduce maintenance requirements.
