I do have all the specs for the valve adjustments.  I will try to get it out and post it on here soon.  It is quite easy.  I also have a copy of a service manual that I am willing to sell.  Please email me if interested. -Jeff jeepcj_6@yahoo.com

Ok.  The instructions read that they have numbered the valves starting at the front to the back 1-12.  2 per cylinder.  so 1 and 2 are for the first cylinder, 3 and 4 are for the 2nd and so on. #1: Run engine until warm.  #2: Rotate crank to bring #1 cylinder to TDC on compression stroke. #3: Remove valve cover       Adjust the following while still hot...  In parentheis is the valve in order from front to rear.        Ex #1 (1)        In #1 (2)        In #2 (3)        Ex #3 (6)        In #4 (8)        Ex #5 (9) #4: Rotate crank one turn to that #6 piston is at TDC on compression.      Adjust the following valves...        Ex #2 (4)        In #3 (5)        Ex #4 (7)        In #5 (10)        In #6 (11)        Ex #6 (12) Adjustments should be made while engine is hot.  After all valves have been adjusted correctly, tighten lock nut firmly to secure the adjustment.    Tightening torque:         Pivot Lock Nut:  22-28 ft lbs    Valve Clearance:         Hot:  Intake and Exhaust are both 0.38mm or 0.015 inches   Hopefully all that helps!  Let me know if you need more!  This is a great manual! -Jeff jeepcj_6@yahoo.com

I have recently rebuit the engine and have yet to start it. Thoughts on valve adjustment cold? Do I make the lash slightly less than the specification or greater? Thanks.
