John owns a crane company. He used 6' and 8' long nylon chokers around the engine and a winch/hoist on a barn beam. Chain would damage the oil pan, valve covers.
But we ended up taking the head off after it was on the frame, mainly because the shop should not have sent the assembled engine back with loose studs that leaked after we added water and ran the engine. They paid for a new head gasket and break-in oil.
Yesterday he torqued the head to 20, then at 40, then at 63 lbs.
Everything on the engine is done now and it runs like a top. We burned in the cam by running the engine at 1200 - 1800 rpm (we used a battery operated laser tachometer) for a half-hour.
John will torque the head again today.
In case you missed it in the Duchess blog, here a photo of the hoist setup.
