You said it before I had the chance to add.

Garbage electronics, though.

Plus you could add some of the creations from Cosworth, Coventry Climax, Ricardo Engineering or Naipier

Here is some interesting stuff on 'F' head engines for some time favoured by RR.

I always thought this a silly idea, but I guess there was some logic in it.
It also illustrates an unusual Rover Almost Hemi 'F' head.

expat, great link (got the Peugeot engine that inspired the Offy as well).

Another thing in favour of the F head was the very cool inlet valve remote from the plug with the spark over the hot exhaust made it more resistant to detonation.

The Griffon was even better.

Maybe pre- ignition, As for detonation . This design would be terrible. .

I do happen to remember that the 'Big' 6 cyl Rovers required 101 octane

But 'that' F head was more like a Hemi

The true F heads would likely had bad thermal efficiency, that might counter detonation.

The crecy might have been incredible!

If I had the money of Google, I would fund a recreation of a Crecy Areo engine, just to hear it.

When tested, it was said to cause alarm 15 miles away!!

By detonation, I take it that you mean end gas autoignition ?

My comment still stands.

Getting the fire over in the vicinity of the exhaust valve, and having it move to a cooler area is better for detonation...flame still has to traverse the chamber to the quench area.

Would love to find even a video of it running.
