Yes, I would do what Riverbend says with the cylinders.

If there are rusty spots on the cylinders walls the thin lubricant will help polish the rust particles away. The flow of fluid will lubricate and help prevent scratches or gouging caused by any flaked carbon or additive deposits from gasoline being trapped above the rings in the gap between the piston and the cylinder wall.

Rolling by hand a little bit will never hurt anything and provide you a feel to see if things all not seized. The timing belt has set there in one spot for a long time. I would think about changing it as soon as possible or at least check or reset the tension adjustment. It's a quick to do thing.

I would go one step farther and go ahead and use the starter and roll the engine over faster without releasing the injectors to fire gas into the cylinders or make spark.
This will check out the starter ahead of getting things going.

You can do this using the wire that hangs out empty at the back of the engine from the harness.
A wire hook directly to the positive post will spin that starter without a key on!

You want to make sure you get the oil pump paths filled. Getting the oil up out of the pan and into the oil filter is all part of that oil galley.
Bottom line, you roll the engine in tens second bursts and wait ten seconds.
You want to do this at least three to four times or until you see oil coating the cam lobes and where you can tell fresh oil has come out from under the cams journal caps.

You do not want to spin that cam under power too early.
The journals are bored right in the head that's aluminum. There are no inserts. Those upper bearing caps surfaces are definitely dry.
The valve springs have set there pushing up against aluminum caps for years. All the while under that pressure and no oil between them.
The two dissimilar metals can form a bond. Any metal that breaks away from one side or the other will gouge grooves around into the journals.

When an engine or head is rebuilt there is an whitish assembly lubricant, that looks like grease, is laid around inside these journals in case warehouse storage. This provides lubrication there until the oil pump gets things filled.
You don't want wiped out cam journals. You can lose support area of oil films that leads to lower overall oil pressure.

A gift that just keeps on giving!
