John- Welcome to Ferrari Life. Do not know what you are hearing, but the 308s do not have hydraulic lifters/tappets. Those did not arrive until the F355 and 550 were introduced in the mid-90s. Valve clearance is adjusted by removing and replacing shims of the correct thickness to get the desired clearance and hydraulic pressure is not involved.
Is the noise a tapping or more of a heavy knock and did it stop? If it stopped, something was starved for oil after the 8 months of drain down and drying out and finally got enough oil to quiet it down.

Every day I look around, and if nobody is shooting at me, it is a pretty good day.
