When using RSR Rocker Shafts and Shims...

I have a motor w/ RSR rocker shims and the non-adjustable RSR shafts.

What is the lever ratio? 1.40:1? 1.55:1?

I am getting .020" at the cam/lobe face with no shims and I'm trying to figure out what size shims I need.

The goal is obviously .004" at the elephant foot which translates to ~.00285" at the cam face, using a 1.40 ratio.

If I am getting .020" @ the cam face with no shim, then I have .028" @ the valve. If I need a .004" clearance there w/ this 1.40:1 ratio, then I think I need a .024" shim set.

Is this correct?

Does anyone know where to order these shims? Or please let me know if you have some for sale...
Thank you !
