perfectly, no worries.
It's normal for the bore on a head gasket to be slightly larger.
This is good in case you decide to bore the cylinders any larger than stock.

...waiting to see the answer on this. Also, does anyone know what bore the HKS 1.2mm MHG comes in, or does that vary in sizes as well?
Having a gasket 1mm over the size of the bore shouldn't adversely affect the CR, but go ahead and figure it out exactly;

This calculation includes adjustment for the head gasket bore, among all of the other variables.

If you do in fact cause the compression to lower a bit, this is OK, because it will actually make the engine a little more durable, and you can compensate for any lost power by increasing boost a little.
isnt the maximum bore 86mm anyway?
i got mine bored 20thou over and its 83.5mm so 84 sounds perfect..
