Any additional info on these 2.7 engine parts please
 

Hi all,
Whilst my engine was in pieces for a main reseal my wrench asked if I wanted to take any pics. So I quickly snapped off these for the record.
Hopefully they are of some worth.
As I have limited info on the engine, he did tell me it was basically a standard 2.7 (albeit twin plugged) with Carrera (Mahle) cylinders and non porsche pistons CR 10.3:1.
I suspect they are Cosworth Pistons maybe the pic are clear enough to give clues?.
Sorry about the bad quality of pics.
Maybe someone can comfirm/dispute this, also any other tips- like oil pump type if non standard.
He also said the intakes were ground bigger?.
Thanks
Ben
