Engine head and crankshaft gone

[CeylonstonE9]

In my restoration of a 3.0 CS, today I found out from the mechanic that the engine needs a complete head and crankshaft. Pistons and block are savable.

There is no old M30B3.0 engines around me but only a few M30B34 engines from e28 or e23 cars, so I may have to use M30B34 engine parts only.

From my research about the engine head, looks like I can use heads from 1983-88 M30b34 and not b35.

Can I safely use the crankshaft from M30B34 too ?

How about engine parts from a newer E32 BMW M30B30? Are they usable for me ?

I really like to keep original block.

You cannot use the M30b34 crankshaft; that engine had a different stroke than the M30b30. Not sure about the M30b34 head, but the e32 parts should be useable.

Where are you located?

Car is located in Turkey, not many parts around here and cannot bring in second hand parts from overseas due to regulations... lots of difficulties...
