There are two cylinder heads on a V6 3.1L engine.
cylinder heads contain the intake and exhaust valve systems and sometimes the cam shaft(s). the valve system parts are normally the parts that wear out first on a high milage engine. these are all vital moving parts that need to be cleaned,reconditioned or replaced, have their respective bearings replaced, and/or be re-machined.

In the cylinder heads.
To repair the heads on a 1987 VW Vanagon, first, remove the engine from the vehicle, then detach the cylinder heads by unbolting them from the engine block. Inspect the heads for cracks or warping, and if necessary, have them machined at a machine shop for flatness. Replace the head gasket, reassemble the heads onto the engine, and ensure all bolts are torqued to the manufacturer's specifications before reinstalling the engine in the Vanagon. Always consult a repair manual for specific torque settings and procedures.

You have to remove the engine cylinder heads to get to the lifters on the 5.3.
If the only thing wrong with the engine is the cylinder heads, yes you should replace just them, Getting a rebuilt motor is expensive and not needed unless the motor has been damaged beyond repair.
