Bogie, thanks for taking the time to describe that. I appreciate it.
I often find that I have to think in extremes to get my head around a concept. But when I imagine a mega-lift cam opening the valve via a roller rocker as depicted above, I cannot see the roller riding off of the valve tip on the exhaust side. Instead I see it running off the tip on the intake side. What am I not getting here?
And again, thanks for your time.
