Yeah, throughout this conversation, I have been wondering whether or not you actually have a 1961 or a 1962. It would appear you have a 1962, and all this discussion about relief valves was in vain. As already pointed out, there were a number of changes for 1962, a different crankshaft, flywheel, cylinder head, no relief valves and more. but I still don’t think your motor has a compression problem.
Methinks your motor may have had some ID tag numbers messed with by somebody.
