LS7 Valve Size Question

LS7 Cylinder Head: I need to know the Overall Length and the tip length of the Intake and Exhaust Valves that come from the factory.

Does anyone have this information?
Thanks in advance!

THANK YOU. I bought 2 new valves to measure them and took them to a machinist and measured 5.230 for Exhaust and 5.130 for Intake so at least I know that I am close!
