Here is the answer courtesy of my machine shop! The #1 and #7 bearings are wider than 2,3,4,5 and 6. My wider one is on #2 and I am going to move it to the #1 position. Again I don't think this will matter as the middle thrust bearing won't allow the crank to walk and hit those bearings. I took a .020 feeler last night and it fit between that wider bearing on #2 and the throw towards the back of the engine. If the thrust is less than .007 .020 should never be a factor even with heat expansion.
