while i was cleaning my heads for new intake and valve covers i noticed a few of the rockers are slightly loose. what steps do i need to take to fix this? or should i just buy new heads/have these refurbished. its 2 from what i can tell and the movement is very slight. i didnt take a video of my car but the video ill link is identical to what im dealing with. maybe even less movement than his. here is the video.
