Default Re: Head and rockers.

I think your rocker assemblies look very clean...compared to most I've seen in these motors, unless they were rebuilt recently.
I suspect yours has had the top end, or at least the rockers assemblies redone recently.
Some side play is normal and therefore to be expected. You might want to compare to the other side when you get that cover off.
Are the valves adjust ep properly? A loose valve adjustment can make a significant racket.
