i don't know what a stronger valve would be for, except in an engine model that has a known history of burning exhaust valves, or dropping/breaking them. is the 7M GTE one of these? if it isn't, it's seat or lash/gap was probably too narrow.
stronger springs are not usefull at all, because they decrease power output unless they are necessary for stopping valve float, from higher rpm's or an agressive cam.
