I'm building a "budget, low-rpm, highway cruiser" 440 & I'm trying to use some used stock rocker arms.

1. What are the limits of a stock rocker arm? I mean, are they limited by spring pressure, cam size, or what? What are those limits?

2. When re-using stock rocker arms, what exactly should I be inspecting? I think I might have 2-3 in my used set that need replacement.

THANK YOU
