yes i believe so i even triple checked I verified TDC at the number 1 cylinder added my push rod checker until there was no slack i got 6.905 i even double checked that by using the stock magnum pushrod which is 6.900 and there was a little play, so i knew my reading of 6.905 was correct. then added 0.030 for preload total of 6.935.
Depending on thread pitch, .030 is around like 1/4 turn down. I know yours is non adjustable, I'm simply giving that as a point of reference. That's a very light touch with preload. I believe it needs more. I believe I would listen to Hughes.
