I'm doing the same thing...I thought non-adjustables would be simpler, but valve action doesn't seem right, even causing some missing and valve knock in at least one cylinder. Best to have two people to adjust them though when you install them. Each valve will have to be in its closed position, lash taken out, and 1/4 turn extra (opinions vary on this, but that's what I'm going with). I'm just going to have someone turn the crank with a wrench (plugs out) while I view and adjust from the top...I've made a paper template--a circle divided into thirds, that I will put on the crank. each third of a turn, the next cylinder will be at TDC (1-5-3-6-2-4). Of course, you have to correctly have #1 at TDC compression to start.
