Question Valve job on 450 sl?

I have a 1975 450 sl with 150,000 miles on it. The top end of the engine is brand new and the compression is 160 lbs +/- 10. The problem is I have loose valve guides. If I have a valve job done on the engine, will the increased compression make me start burning oil or worse, could I blow a ring? Thanks for any feedback!
