valve springs and push rods

I bought a bunch of stuff and got some things I don't know exactly what they are. I have new valve springs that I have no clue what they are except they are Racer Brown. Do I take them to be pressure tested?? Will it be worth the cost?? Also push rods. How do you measure them? End to end or does the cup indentation get suptracted out? Does that make sense to anybody??
