Actually, I pulled the head on the right side and removed the #1 intake valve unit. The mid stem measures 0.342 while the area immediately above the guide measures 0.344. Above that there is a suggestion of a shoulder and the stem tapers up into the valve head. Pushing down on the valve head to compress the spring results in the valve stem becoming "wedged"in the guide opening. It seems that this might prevent the valve from seating properly once the clip is put in place with the resultant spring compression. Any other thoughts or suggestions would be appreciated. Thanks everyone for your help.
