If you've ever checked geometry with a few different brands on the same engine, than dynoed them, you would be suprised.

Re: rocker arm ratio
I got into it with the Crane guy on LS1tech about those things....
Basically they just lower the pushrod mounting point on the pushrod side of the rocker.... makes a different path for the roller to sweep on the valve and a "faster" opening... I guess, not a huge fan of them, BUT on a small cam motor they would work really well.
