No start...timing good...leak test bad...need help

"Sticky Lifters" - is his because over the long period of disuse they drained most of the oil out of many of the lifters?
If so, no amount of churning with the starter motor would re-fill the lifters . So the lifters must be replaced ? Quite a job and a significant expense. Well worth doing some more diagnostics first to verify simpler issues are not causing the problem.
