CC volume of 3.0l RSR heads.
 
Does anyone know the factory spec for the combustion chamber volume of a 3.0l RSR head?

Thanks in advance

Richard

I found an old thread in which Tom posts re. his 3.0l RSR clone. Is it (factory) spec 84cc?

it seems to me a real RSR head was as Aron says I seem to remember 78cc flat inlet valve terribly heavy.

The 2.8 RSR was a horrible arrangement. The 3.0 was slightly better.
