High rpm miss

B3RE. Thank you so much for explaining this to me. I must be reading the wrong material. This was tech from a reputable cam maker. Said to change push rod length to get sweep centered. That's the difference between me a garage builder and a pro like yourself. OK. Went out and put in a .150 longer push rod. Sweep is down to just under .040.and right at about .100 from the edge. This is the original set I ordered but they didn't center the sweep. So I went shorter. 7.1 to 6.950. Am I close enough or not? OH! and I think their small block chevy valves. Thanks again for sharing your knowledge. I'll try the sbc rocker to see if that helps if what I have wont work.
