Sorry, .033 longer, not .33
I bet .050 would be better, but the 6.933 were only $23.00. When I get it dialed, I'll get some real pushrods. But for now the difference is night and day.
Measuring pushrod length with pedestal rockers sucks for sure. I made some solid lifters which helps (only tighten to zero lash), but still very subtle differences.
