On a side note the small block drivers side head oils when the dampener is at 20 ATDC #6 compression and the passenger head oils when the dampener is 90 degrees (1/4 turn) or 5.693" around the dampener BTDC #1 compression and a big block oils when #6 and #8 are at TDC compression (I forget which head is which). With cam/lifter failures being what they are I like to minimize cranking.
