What I’ve seen on the few chevy’s I’ve fixed wasn’t the peak “lift” of the lobe, it was wiping the material around to the base circle of the lobe and never allow the valve to fully seat. That would result in a misfire.
I'm thinking it's got to do with pushrod length. If it's not supplying constant pressure on the cam when it's at the small part of the lobe, it won't be contacting the lifter enough to cause it to rotate.

Maybe someone knows and will comment, good luck bro!
