Roller Valve Spring vs FT Valve Spring

Garrett Ellison said
I'm looking for the inner step diameter of the 9736 retainers, and I will go from there with Mr. Wallace's spring calculator. Do your valve springs have a damper? We also need to confirm beyond a doubt those are the P/N's for the components.

They are just a spring and damper. There is no innerspring.
I'll have to check on what the spring number is cuz I don't know off the top of my head.
