Ipok,
for a 67mm bore you will need a 67mm gasket. |

| I don't have one laying around but the thickness should be in the range of 1.0 to 1.5mm |

Hi Axl would you fit a copper head to my motor as described above I'm only using it for street use I think it has high compression as the pistons have a dome on them, some people are telling to use a composite gasket as the copper one will need an O ring in it, what are you ideas, hoping you can assist IPOK. |

| You don't need an O ring with a copper gasket. I would prefer copper gaskets over standard - they conduct heat better which minimizes head warp, and they are reuseable. If you want, you may put a light coat of Loctite Ultra Copper or similar on them before mounting them. |
