Whoever said that cylinder heads were easy to remove never worked on a 20+ year old engine that has been sitting up for awhile! It took a BFH and a crow bar, but the heads were FINALLY pried off (thank God no damage inflicted on them). Valve lifters & crankshaft pulley removed. Pistons and valves look in good shape, the valve lifters were clean, no nicks or scratches. Crankshaft still isn't budging. Tomorrow I will lift the engine, drain the oil, and remove the oil pan to take a look at the crankshaft.
