CB900 Custom oil stopper on valve head

[AOrhun_imp]

Hi everybody,
I own a '82 CB900 Custom which I cherish.[/size][/font]
I had to do total strip down of Valve Head recently. Among other things I have seen the "Oil Stopper Plate"s (Part no 12241-425-000) situated on Cam Shaft caps B and C are in bad shape and these small parts are not available any more.

Does any one know the function of "Oil Stopper Plate"s (Part no 12241-425-000) situated on Cam Shaft caps B and C ?

What happens if I omit installing them.
Thanks for your inputs.
Best Regards

even if in bad shape best to put back in they fit lots of other bikes look on e-bay for a head that may have them
