Lurch,
Unless I don't understand the whole deal, I think it's REAL weird.
It seems to me that without changing the pivot point, the only way the achieve any "hi-lift" out of this style rocker is to fudge short on the pushrod end, or fudge long on the valve stem end.
Either way, the geometry is going out the window. I am guessing that is why they recommend stock pushrods...the skinny ones, so you can crowd the pushrod over a bit to fit the shortened side of the rocker arm.
If you lift the intake a little more, and allow a little bigger charge into the cylinder, you better do the same on the exhaust side, or it seems like you are wasting your time...a full "inhale" but a partial "exhale"..weird. :confused:
