[quote=intocarss;471936] It's not the proper way... but sometimes you have to grind some on alum rockers to clearence big OD retainers and springs Or install lash caps or longer tipped valves or different retainers if "installed hights" can still be achieved correctly
Thank Jer, I was not aware that engine builders sometimes have to grind on the rocker arms.

If you're asking If the rockers hitting the retainers due to chain breakage The answer is...very unlikely..Hard to tell by the pics, Those look like they've been hitting for a while
I agree Jer. After further observation it's pretty obvious.
What exactly are you trying to figure out?? PM me if you like
Trying to figure out why the rocker arm is hitting the retainer and why the engine builder did not catch this.

In this pic, is the roller on the rocker that far back on the valve tip w/ the valve closed, is there lash?? If so your push rods are wrong or that rocker is hitting the retainer and pushing it back
Stand by, the pic your refering to has not shown itself this time around
OK I see it now. In that pic #1 is at TDC and both valves are closed so to answer your question, yes. I hadn't checked lash yet as I was trying to figure out if I was going to need the lash caps or not.(Seriously do not recall having lash caps when I pulled the heads off)Obviously I do. I'll have to run down this morning and confirm but If I go with a longer pushrod I'm not sure I will be grabbing enough of the rocker stud.
Here is a dumb video but will give you an idea
