I did it differently. I used two very week springs like springs used in vac secondarys but stiffer, all done with hydraulic lifters, no clay, just to make sure I had no piston to valve interference. one very week spring on intake valve, one on exhaust on number 1 cylinder. I started with the piston maybe 10 degreese BTDC and slowly rotated the crank with a torque wrench on the snout of the crank till I was about 10 ATDC. while rotating it I would push down on the valve making sure I had sufficient clearence. at the tightest spot I checked distance with an indicator just to see how far the closest clearence was. I did this with no head gasket so I didn't have to worry about closer tolerences after I torqued the head down. Strange way of doing things, but it worked...
