Cylinder Head Casting Number from 1985 NOT a "200"

[Tiroler]

Has anyone here got information on what a cylinder head from M20 block this might be?
126 4166 (with 85 also cast in a circle)? My gut tells me this is from euro e30 in 1985
and a predecessor or variant of the more common "200" block. Probably a euro E30 323i or 325i…
Just curious.

I have no idea, but don't forget they made replacement parts long after they stopped putting an engine into cars. For example, I had a 2002tii head with a 1985 date mark on it.

If I remember correctly euro E21 320/323 had "200" head. Euro E30 320/323 had "731" head. This is something else...
