What does code on the Crane Roller Rockers Mean?

Anyone know what the stamped code on a gold Crane roller rocker means?

36-160 (I'm thinking it means 1.6 ratio but not sure what the '36' is for)

Then below that it shows a stamped 'star' and '-11'

Can anyone tell me what these are? I'm removing them from the aluminum heads I was going to use and will use them on the new aluminum heads.

Hey guys, just thought I would follow up with an FYI for you. I sent that picture to Crane's Tech Dept and got a quick response from them.

-The '36' is Crane's indicator that the rocker is designated for a SBF
-The 1.60 is (as suspected), the rocker ratio
-The '-11' is internal manufacturing info per Woodsnake's suggestion (good one!! )

Just thought you might like to know for sure.
