Are you saying that you can hear lifter/rocker noise?
Valves with too much lash will open late, and close early. Valves that are too tight will open early, and close late.

This is were my exhaust needs to open 154 degrees Wich is 26 degrees bbdc and close at 358 Wich is -2 degrees+ -2 degrees Wich equals 204 came lobe. And intake opens at 355 and closes at 591 if u put it on a 360 degree wheel that would be 5 degree btdc and closes at 51dgrees abdc Wich equals 236 cam lobe .and I think is 3 degrees overlap bc -2 and 5= 3 over lap

I'm sorry guys this case study was a year a go but didn't want to leave it open without a fix ,the problem was I didn't analyze the waveform .and the problem was in front of me the whole time it was a tooth missing on the crankshaft signal plate when I was looking at the known good cam and crank I thought it was ok but I missed it .
