I did check the firing order, it's correct. Unfortunately, that pretty well narrows it down. Good thing the garage at Pappaw's has a furnace because this sounds like a winter project!

Your intake rocker/valve will be by your intake port and your exhaust rocker/valve will be by your exhaust port. Hope this helps.
