I know with a lower pressure cap, your coolant will boil over at a lower temperature, but at the same time, you are putting less pressure on the cooling system and less stress on the old radiator hoses. As long as the coolant is at a 50/50 mix and doesn't reach past 240 instead of 260, I would say it is fine.
