Why would you hear a tapping noise when your Chevy cavalier is running?
A tapping noise is generally the result of a bad hydraulic lifter, plugged oil passage to the lifter, or bad tappets. Sometimes just changing to lower viscosity high detergent oil will cure it. Or "Any automotive oil additive with the word MIRACLE in it".
What are tapping valves?
Tapping valves is a noise made by too much clearance between the valve lifter and the valve. Modern engines have hydraulic lifters. If you have too little oil pressure or run the engine low on oil, the lifters will make noise. The lifter can also wear out.

It's a rocker arm tapping at valve stem. Hydraulic lifters (hydraulic rocker mounts) are the common reason for the ticking. If it doesn't go away when the engine heats up, consider replacing the lifter where the ticking comes from.

Why would a 1995 GMC 350 make a tapping sound when cold that gets louder when warm?
If it is a Tapping sound it is normally a lifter. Could also be a cam, pushrod, and or a rocker arm. Tapping is normally upper motor. If it is a knocking noise it is normally in the lower motor. If the noise gets louder when warm most likely a lifter is going bad. As the oil heats it thins slightly causing more oil to bypass inside the lifter which it is not supposed to do
