Replace rocker shafts for sure

Hey YR,
Are you figuring those numbers off of the valve side of the rocker only? And if so, are you setting it so that a line from the rocker shaft axis to roller contact tip is 90* to the valve axis at mid lift?
Tnx.


I measured the thickness of the shim and I forget how I came up with how far back the shafts were moved...IIRC I put the shaft on without the shims and took a measurement off some fixed spot. Then I put the shims under the shaft and measured it again.

I will double check my numbers when it goes back together.
