curious about valve lash setting/check

Rusty, this engine has been run by another before me with the notches both in the rear (and a bit by myself), so I'm guessing I may have other problems? I get both notches pointed down, passenger side in rear, and driver's side in front. this threw me off, as I had posted to AJ that they were both in the rear. that's why I couldn't understand 'front and rear', instead of position. thank you, and all others that have put up with me, LOL, I truly appreciate your help/knowledge. seems I have some work ahead of me :)

No problem. Hopefully you haven't had any damage. Correct it and see what you come up with.
