what heads you use is independent of the mileage on the engine. if you were satified with the way the engine ran/runs (compression/oil consumption/oil pressure/etc), just swap heads.

BB heads come in open and closed chamber and even the open chamber have several different volumes. What do you have on it now - original closed chamber iron heads? You will need to match them reasonably closely to avoid a significant compression ratio change. Going to aluminum makes higher compression engines more forgiving of today's gasoline so you don't really want to give up much if any compression.

Sure why not drop some weight and performance at the same time
And no it wont blow your bottom end out before that myth surfaces again.
