I don't know if this is going to be a pretty stupid question so please bare with me. I've been researching and trying to figure out what the valve lash on my motor should be at. Im running a 72 Olds 350, eldebrock performer rpm cam, and roller rockers. Everywhere I read said to check the cam card for the valve lash setting. So I check the edlebrock website find my cam card and I don't see the lash setting. I then read the description of the cam and it says that the cam is supplied with hydraulic flat tappet lifters. So I started researching hydraulic lifters and started confusing myself because I read that hydraulic lifters don't need to be lashed? So my question is do I need to set my valve lash? If so what do I set it at? I attached as many pictures as I could. Thanks for the help in advance.
