Someone once told me that the EL 4.0 has a different rocker ratio to EA-EF. Does anyone know if that's the case?

The EL's have different lifters but I don't think the ratio changed.

Late EL changed to the AU low inertia valve train (smaller valve stems and rockers etc
not 100% sure if the ratio changed, but the later EL rockers aren't interchangable with EA-EF
