Valve Lash Adjustment

Plugs are brand new. I thought maybe my rough idle was a plug issue so I changed them first. When that didnt fix the problem I thought we may have overtightened the lash when we made the first adjustment. Then I started chasing the valve lash issue so I need to get the lash dialed in and if I get another noisy valve I will be sure to check the plugs for indicators. Good tip. Thanks.
