The first Scania V8 was an ENDT865/866 with individual cylinder heads.

Are you saying that the first Scania V8 was a Mack engine? Interesting.

Yes, born from Mack’s long time relationship with Scania, and the old man’s idea to gain economy of scale via such an agreement.

Why did the Scania versions of the Mack V8s have individual heads?

Because that was the norm in Europe at the time, owing to it's advantages.

Scania's feeling to this day is that individual cylinder heads have several advantages. A cylinder head covering more than one cylinder imposes restrictions on the maximum potential for achieving efficient intake and exhaust flow, because provisions for cooling and clamping compromise cylinder head design. Since individual cylinder heads don't suffer from these obstacles, the head design can be optimized for rapid gas flow to achieve maximum fuel efficiency.

And regarding maintenance, it's much cheaper and faster to remove and reinstall an individual cylinder head, than a single cylinder head covering two to six cylinders.

Excellent and educational explanations on the single head per cylinder. Is there any reason the American manufacturers didn't adopt this style for its advantages?

At a guess I would think it's more expensive to manufacture as on a V8 you have 8 heads to machine as opposed to  two or 4 on a E9

So at least twice the setup for machining and twice as many heads to machine
