valve lash on 1988 325i

I am going adjust the valves tomorrow on an 88 325i that has 176K miles on it...bought it 9 years ago with 82K on and didn't have to adjust the valves until about 4 years ago, which was fine. worked fine each time (about once a year) but it's been getting a little worse the last 2 times...the adjustment doesn't seem to last as long, engine still runs fine and all, just more clattery each time. Question is; I am thinking of going to .010 as with 4 cylinders instead of .012 as I have been doing as recommended for the 6....I am thinking of tightening these babies down as I can't stand the tapping and feel that possibly, I might be looking a head rebuild down the road anyway. I know that valves not fully closed are worse than what is right now. Yet I know the valves are fully closing as I can hear them via the valve train. I feel this may be the old valve stem run-out syndrome...anyone else taken this possibly ill-advised route? and what happened? I hate noisy solid lifters, drives me insane (not a far distance of course). The tick does get better as the engine warms up, as it should be, but I am still not satisfied and know they need adjusting again...To summarize,I am considering adjusting the valves closer to remove the ticking after warmup due to general engine wear and tear. I am wondering if anyone else has done this and how did it work out? Thanks...cliff
