How much valve pressure can 5/16 rods stand?

Check with the specific manufacturer.

I'm using CompCams 7997-16 Hi-Tech™ 5/16" Diameter pushrods. More info here:
http://www.compcams.com/Produc...27Pushrods%27-3.aspx

And those are being used with Lunati (74820-16) Pacaloy Beehive valve springs. My spring pressures follow:
Seat: 155 lbs.
Open: 377 lbs.
Rate: 370 lbs/in
