[alfa] Compresion Ratio modification



If one has a 2000 GTV engine with 10.4:1 pistons, SPICA injection and has problems with knock / detonation - is there a reasonable way to lower the CR with some form of special head gasket - I calculate that I would need to add about 0.8 mm or 0.032" in space between the head and the block to get it down to 9.5.

Any experience with this kind of problem out there?

In an old fashioned solid block engine, one might just add an extra head gasket, but with the Alfa wet sleeve setup, do not know if this is a feasible solution - would guess NO.
