While it is true that the Tech Dept checks valve lift at the retainer, we can still check rocker arm ratio if we so desire. That could happen anytime we run across a set of rocker arms that do not appear to be correct. A racer was DQ'd a few years ago at Gainesville for using 1.6 rockers on a SBC even though the lift at the valve met the spec.

(Disclaimer: Opinions expressed by me on this forum are exactly that, my opinions.)
I suspect that would be a tough one to handle since you (I assume unless you correct me) do not have a tolerance. Since a 1.6 RR may check out to 1.53-1.55, is that within the tolerance allowable for an advertised 1.5 RR?
And if the tolerance is "dead nuts", you would be able to throw just about everybody out. Right?
My guess is somebody in Gainsville a few years ago must have really PO'd a tech guy off to get bounced for that...
