It all seems very difficult, we always build them, warm them up Dyno them, if it is right race it. If not tune it on the dyno, we never used any other oils than what we raced, and do not believe letting them run on the stand. There are a dozen ways to do this, unfortunately many methods fall back 50 years to a time when materials were different.
Xcell racing we find the leakdown through the spark plug hole tells us everything we need to know, I can say it is almost a 100% correct diagnostic tool when used properly.
About the only common denominator I see to our practices is an early oil change after the build, have a look at the oil, and go race.
