Valve spring options

I would run a Comp 901 on that so quick, it'd make your head spin. Remember, the small block has an unruly pushrod angle. That reduces total lift at the valve about .020". Right in the 901's ball field. Even if they had the full .513 at the valve, which they don't, the 901 would still work. It's just not that hard.
Comp 901 Im assuming these are springs?
