Rocker Arms---Does an official clarification exist

[Rusty Davenport]

I have been talking with some of you about the question of rocker arm ratio that has been hammered on several previous post that I do not want us to unpack again---SO---the burning question is----does an official published document exist from NHRA tech covering all possibilities and doubts concerning rocker arm ratio being factory stamped on rocker arms as shown in engine specifications for visual inspection regardless of how it checks ??? I hope I did not ask that incorrectly. I would like to thank Alan R. and others for talking to me about this, but is there anything in writing and if not why not ???
