I just got my block back, went from 86.5mm to 87mm pistons.  
My head gasket is boxed away somewhere, so I haven’t measured it, but I have a quick question for anyone that’s familiar with these.

From what I’ve seen on the HKS site, all of their SR20 gaskets are 88mm.  
Obviously this would make it fine to keep using, as long as the thickness is fine.

I know that some gaskets go ahead and use a bigger bore with a smaller piston for example having a standard 87mm gasket for stock 86mm pistons.

Anyone have any experience with the HKS gaskets, should I be fine to use it?  
I think so.
