MRE roller rockers on Trick Flow heads

I never liked the half mood spacer idea either.
At TrickFlow when they designed the heads, there were probably plenty of design iterations before they settled on a final geometry. The mid-lift rocker geometry has been around for decades, and this was not TF's first cylinder head design. There have to be reasons they recommend Harland Sharp rocker arms which MRE rockers are a version of. There have to be reasons that Trickflow is staying with their geometry even on their new 270 max-wedge heads.
I will mock up additional rocker geometry, do some more research, and ask more questions.
thanks.

Could it be marketing?

We should all know by now, there is no one correct stand height, unless it's like the W-2 and you use the exact valves, rockers etc.

So claiming TF put the stands in the correct place...for what? You change stem height, it changes geometry. Change rocker arm manufacturer and the geometry changes.

It's all part of one system where every part affects the whole.
