I guess the lack of anser comes from the fact, that we do not know which car (type, model year) the cylinder head belongs to. "731" doesn't say anything to me and probably to anyone else ...

Based on my extensive research and practical trials on M20 heads, I know there are lots of numbers on the heads in addition to the part number. But due to the stress I have deleted all memory of exactly what numbers and text are on a M20B20. And I don't have on nearby to look at...

I will look up the number of my B20 head and post it here, hope it will help your research.

Because much English is not proud, I'm sorry. It is the question about the engine of E30-323i. There are 731 '' and '731,' and an aluminum casting of 'MADE IN W.GERMANY'. Please teach what kind of process these are used by.
