Origins of a 9E1-AF cylinder head

[Ruairidh Dunford]

Can you elaborate on what a “Works Only” car is please, Chris?

Can anyone help with this, please? Daisy has some 9B parts on her Sports Van...

My assumption would be that David means they will be "special" parts that were only on the "works" cars, IE GW 82, Grass Hoppers etc.

What parts are they? (And pictures would be ace.)

Thank you, Austin.

I will let you know, not very many, so don’t get too excited!!

I wonder if anyone has an idea what this head came off. Number reads 9B 1175 or 8

Hmmm it doesn't look a bit like the replica Gr*sshopper head on Tony Betts website.

What does the combustion chamber shape look like?

[Lowespeed]

The head is thicker than standard heads and need longer studs to fit. Interesting swirl patterns formed in the carbon; used of blown engine.

Thanks Andy, 
 have you measured the combustion chamber volume? 
  Best wishes, Robert.

[Lowespeed]

The combustion chambers averaged out at 40.8cc; giving a combustion ratio of around 5.6.

I’m wondering if it’s a Gordon England creation, but not sure how that squares with the B part number
