If they are only showing hairline splits they are in pretty good condition and you have nothing to worry about. They are quite thick and don't often leak, even with what looks like fairly substantial splits in them.
As for the heat affecting the rubber solution I don't think it would be a problem as things don't get all that hot on the inlet side.
