911 engine block 4R 5R

I have an engine block for a Porsche 911 and am looking for information regarding its value and interest in the market. On side has 901.101.101 5R and the other has 901.101.102 4R. Engine # 6124345. Assuming this engine is magnesium? Not sure of the miles on it. Any info would be great.

Thats a desirable '72 911T mag case.

ALL of these still need the full suite of machine work for durability, however those engines didn't run hot and stress the case at all thus making a good candidate for restoration or some performance improvements.
