I finally got my motor fired up last night , but things just didnt sound right

, I figured it had some little problems from sitting so long and it was late so I would fix it today. Today I went out to play with it and saw this

( rockers hitting the valve covers )!! WTF these are the same valve covers I had on the motor last year , and I didnt change anything in the motor !!! All the rockers are still tight, nothing loose , cant see anything wrong

. I know it wasnt like this before, you can see the valve cover move and hear the noise when it cranks over

.
Also this is only on the right side of the motor. No I just looked closser ,its on both sides , but the left side is not as bad, it's the intake rockers only.
Anybody have any idea WTF is going on here
the rocker arm

the valve cover ( look just above the d )
