I just read this whole thing & it hurt my brain. I only have tried once w/ solid cam (lunatti) & set my intake & ex to.26. I used the remote start, & worked my way to each int/exh. It seemed to me that the duration/lash stayed the same once set... never picking up or loosing tolerance until lift came in to play. As a complete rookie, I hope I did this right. Here's my question- as long as my motor is setup this way, will the valve lash always remain the same? As it breaks in & wears, wouldn't the lash/tolerance change slightly over time?
