Autodata has nothing on that engine sorry.
As for oil, only thing I could suggest is using what is recommended for the F series engines of the same era (that is what the G series most resembles according to Wiki). Of course quantities will be different though. Ratings should be the same.

Permaseal has head gasket torque ratings:

I would imagine the data I have regarding torque values wouldn't be correct for your engine though sorry.
