<VV> Engine identification.

[Doug Mackintosh]

Unfortunately the YN code was used for both 145 and 164 Cu in engines in different years. If it has a harmonic balancer rather than the simple pulley that would make it "likely" a 164.
Your pushrod tubes should be covered by the shrouds (see attached photos with shroud installed and shroud removed). Sounds like one engine is missing the shrouds.
The head numbers are at one end of the head, and the heads are interchangeable from side to side. So the number is on the rear end on the right head, and on the forward end of the left head. See attached photo.

Ok, my 'older' engine is TO327YN, and my 'newer' one is TO712RD. I 
presume the head numbers are towards the front of the car, as I can't 
see the numbers from the back of the car? What I can see, however, is 
all the pushrod tubes on both sides of one engine; there are little 
square panels that are present on one engine blanking off this view, but 
these plates are absent from the other engine. I presume they should be 
in place?
Both my fans are non-magnetic, so I guess they're magnesium?>>
