Also any ideas on which head gasket to use - 2.0 or 1.8 (1.8 bore 80.6mm ~ 2.0 bore 84.8mm)??

Was hoping that someone would have tried this before! I assume that the 130 spec head and cams must be good because they make the 1.8 130BHP - the same as the 2.0 as standard? Would the head make the 2.0 more than 130???
