This might help you a bit. I fitted the the 2.5 mm thick 90 hardness rings after reading this and they've been fine

I went through a nightmare around DS aftermarket gasket set tring to fix an oil leak.

 I ended up using the aftermarket O rings along with a proper Honda OEM gasket plus having head skimmed.

As many have said the relative thickness of head gasket and O rings is critical to getting a oil tight seal.
