928 heads

I found some rebuilt heads. The person selling them does not know what year they are. My car is and 85. The number on the heads that are for sell is 1043454rK1947. Does anyone know what this number means?

I'm sure when one of us gets home from work we can look it up

Found out they only have 8 valves each, must be earlier model than mine, but if someone needs a set of heads these have been totally rebuilt even welded up where the water flow had caused some wear and resurfaced.

Not sure how that number translates to a 928 part #.......I just looked at PET for 2 valve cyl. heads.

Thanks, for your effort!
