what did the b1800 share an engine with?

hey guys, me again. so I finally tore into the engine in my b1800. I need a new head. I was wondering what else had the same engine. I think everything's interchangable just about with the same era ford courier, but I don't know what other mazdas it shared with. any info would be nice.

I think the Ford Courier is the only thing that will cross-reference. To my knowledge nothing else from Mazda shared the 1.6L and 1.8L heads from the pre-1980 B series other than the Luce which wasn't available in America.
