M60b40 ----- M60b44 parts question

Hey,



Just to note before, I have searched for the answers to these questions and have come up short on a solid answer. Maybe I was using the wrong terms or I just suck at searching. But whatever.



soooo.....



Just went to my local You-pull-it (junk yard) and found a 740i (not sure if e39 or... something else. it was totaled. Looked like it got hit by a bus, on every side...twice.) Funny cause the interior was undamaged. Germany safety saved the guy in this one.



Anyways....



I was able to pull the intake, injectors, fuel rail, 4 coils and the driver side valve cover. Could get the heads if someone wants it. (they say its under 200k :shifty So vague) Valves look good, and so do the camshafts and the chain. Couple M cars (two m3's e36 and e46 i think) if someone also needs something.

the passenger side suspension coil is through the passenger valve cover, so that's not an option.



My question is, and I have had trouble searching for a solid answer;



is there a difference in size between the intake manifold of an m60b40 and a m62b44?

Can the injectors of a m62 be used in a m60?

Are the valve covers of the m62 made of Alum? (they seemed a different material than my magnesium m60b40 covers)



Just curious, I've read about this in other forum posts but was not a clear answer; If you use m62b44 heads on an m60, will there be a bore gap between the heads valve area and the cylinder bore? or vice versa, m60b40 heads on a m62b44?





Also, a side note, Not sure if anyone would know... But can i steam clean my engine (portable steam cleaner gun) (gunky areas around the block/headers) As long as I avoid wires, seals, etc?





thanks mates.
