Theres not a lot of info / tests / anaylisis about, on these engines.
Stuff ive seen said the first lapped piston unfinned head versions ran hot / overheated ,
so were duely changed to twin ringed alloy piston and finned head .
Im particularly intrested in the crankshaft diameter / case shaft bore , Bolt head pattern / same as .60 B.B. ? , and cyliner outer diameter / case cylinder bore diameter .
Unless you waNNA DONATE ME AN ENGINE ! . S?P

I have all of those you have listed. The heads are not interchangeable with the BB engines of same displacement. I have found 2 different versions of the 51. One has same size head as the 45 and the other is much larger. I'd post pictures but it's too much hassle on here.

I had two of those none bb .56 motors. I have never seen them with the ears on the case like in that picture.
Less powerful than the bb version but a very good runner. I hard one in a supper duper zilch
