Light weight valves

Does anyone know the effect of light weight valves in a flat head motor? i'm considering stepping mine up with some 5/16 or 11/32 stem valves to save a little weight in conjunction with titanium retainers I just don't want to throw the money into it if it wouldn't help things out. I'm looking on one hand gravity will help them close and possibly help with valve float and on the other the lighter valve train will let the spring work more effectively. Any input would be great!
