They have nothing to do with the actual casting.

Are you wondering what type of heads they might be or when they may have been cast?

I know they are later 10 bolt heads and have the better valve stem seals, just seem to have a crop of odd numbers !

Could they be ID numbers from a previous company that worked on them?

Someone maybe stamped some numbers on years ago...so one day he could annoy someone in the future who might wonder..WTF are these numbers

Nope nothing to do with them

I guess the LF and RF means Left front and Right Front so they could not get mixed up.... Dont laugh!! The heads I now have were made with the rear oil holes blocked off for some reason. So If I put them on the wrong side I have no oil to the rockers??

Possible Perry ! i'll strip the heads and block down when I need them/find time, it's not on my priority list till I blow the 3.9 up !

Do these head numbers mean anything to anyone ?
