I'm not sure this is of any help but I live with valve lifts and springs where you can use the stock stamped rockers. I mocked up enough of a block that I could measure the lift of a stock rocker keeping everything else the same. I took a whole pile (literately) of lifters and measured the true lift. The lifts were all over the map. What I ended up doing was grouping them into groups with relatively close lifts. Racer Brown used to recommend using the higher lifts on the exhausts so that's what I did.

I wrote down all the results but for the life of me I can't find it. Some day.....
