Cooling system pressure

I will be running Evans Waterless Coolant in my 340, block has been dry since it came back from the machine shop, all new hoses, new radiator and heater core. My questions are...since this product has a boiling point of 375 degrees, is there any need to run the standard 16 pound cap? Will a lower pressure cap be easier on the system? What would you recommend ?

No need at all to change anything, and if I was going to change anything it might be to use a lighter cap and a good recovery system.
As mentioned though, they do say no change needed.
