Composite or Copper Head Gasket..

Personally I’d say copper every time. It’s malleable so gives a better seal, particularly on less than perfect surfaces. It also conducts heat better between block and head.

It's strange most Minor experts recommend copper but the Mini boys swear by the Payern composite ones. If you do use composite then it's advised that the cooling system is filled with plain water for a while to expand the gasket.

Done my headgasket twice now ( first, replacing a copper gasket which split between back two cylinders, and second to replace the head) used composite fibre gaskets both times, no issues yet.

Cheers guys,
Job done, got a kit from ESM.

I think I might have best of both worlds as the gasket was Copper on one side and composite on the other..
