BEST 'ERGO' ?

I can’t believe the fixed head engines were pulled due to a height problem■■?
This coming from a company that had no trouble modifying the cab for the Marathon, or splaying the chassis to fit the GM in the Crusader.
A company that manufactured trucks as futuristic as the gas turbine powered prime mover or strange engines like the L60 horizontally opposed tank engine.
To me this engine was a fail from the get-go and it took the bean counters to finally do the deed.
Why a fixed head at all, what were they thinking.
OK they had a cylinder head to block sealing problem, it could have been solved without resorting to this idea.
Most modern high powered diesels today have twin overhead cam and a head gasket…can be done.
