If I remember right, an 86 mm head gasket will work. But that is really preferable for when the block is bored over. I predict that you are going to get a lot of "it will work" type responses, but a stock sized head gasket might be a better choice if you can change your order.

Isn't stock bore 83mm? At least it is according to page EM-75 of the TSRM.

In any case, I believe that the oversize gasket will work fine, but I would rather get the correct one myself. The 1-1.5mm lip around the cylinder bore may have some effects on the combustion chamber, and will provide a toehold for combustion pressure to separate the head and block.
