Replacing the valve stem seals on a K8 with the engine in the car would be almost impossible. At least on the rear head.. no way to get to the valves unless your a very talented contortionist

If you remove the rear head then you could replace them and reinstall the head. That is doable but still a lot of work. Lots more valves to work with on the K8

Btw.. I completely agree with wytbishop. Replacing the valve seals alone wont change the compression or affect the piston rings at all. Removal of the head.. well if the engine is in bad shape.. eh.. maybe that could cause issues.. stranger things have happened. I always recommend replacing head bolts too.. or at the very least.. use a tap n die set to clean both the bolts and the bolt holes of the engine block prior to reassembly. Nasty threads WILL change torque specs. You might think you have only applied a certain amount to the bolt when retightening.. but it could easily be more or less or the torque could relax after the engine has heated up and cooled down a few times. Its not cheap to replace them and certain engines actually Require it when doing a head removal/replace. Shop manual should tell the tale there.
