Hy,
these are the latest photos of the head, cahamber and inlet side. poor quality, sorry.
This engine it's a 982 ( 965 enlarged ) engine just to try the modifications in the head. I also machine down the flywell ( 0.5 Kg Lighter ) and fit a better camshaft ( I'll tell you the degreees ) and feeded by a twin choke abarth carburettor and a 4 into 1 with sportier exaust.

In the future i'm thinking to build a better engine, 1050 cc and abarth head with bigger valves. I'll keep you informed.
Regard's
Flavio
