No. Don’t pull the head. Like fleetwin says, don’t tear this thing down needlessly. Do the Sea-Foam trick first and get the rings loosened up. I don’t think there is anything mechanical wrong with this motor, if it ran last year. If the head gasket was blown, your readings wouldn’t be this high. The Fleetwins have pretty good and strong head gaskets (much tougher than the 5.5’s) What is the conditions of the coils? Are they still original? If so, there’s your issue. They may spark but it may not be strong enough to run this motor. "antique coils" can degrade, just from sitting.
