After taking my head off and swapping it for the Blydenstien A pack jobby i noticed some play in the pistons, was wondering if it was worth boring out to a 2.1? would there be many gains in doing so? any downfalls?
would "normal" pistons be ok, or would it be advisable to go for some forged ones, like the omega 88mm ones for £387?
Also, would it be worth fitting a metal head gasket & wasted inlet valves?
