9.15" it is.
I re-checked my pushrod length using 9.1", 9.15", and 9.2".
9.1" gave me a pattern about center.
9.15" gave me a pattern just to the exhaust side of center.
These checks where with a hydraulic lifter pumped up and a week check spring.
My thinking is with my lifter pre-load added in, 9.15" should be just about wright.
Watching the rocker arm move through its stroke, 9.1" seemed to give a more even movement looking closer to 90deg at 50% lift.
Any one have a good set of 9.15" pushrods with at least .080" wall for sale?
