Default Cooling System Pressure

What is the stock cooling system pressure rating on the LS1?

I am curious, because i would like to get the Mr Gasket Thermocap...but they only have it in 16psi at the local advance....

Thanks!

My new Howe Racing Enterprises radiator specifies a 22-24lb cap so I will call the monday and see where to get one cause everything around here is rated 16-18. Still prolly be ok with one of those for my application.
