With a set of 86.5mm pistons would the 86mm headgasket work? or do you go with the 87mm?

Thanks

I would have to say 87

I posted a similar thread earlier this week about my HG.
A lot of times, depending on the gasket, they’re already “oversized” or able to accommodate a larger piston.
For example, my HKS HG only comes in 88mm, and is used for everything up to that size. The Apexi “stock” HG is actually 87mm I think, so check out your gasket, and just make sure it’s as big or a little larger. A mm in diameter is pretty small, but larger works.
