you would need the 90.5
stock bore of a kade is 89mm stock hg size is 89.5
so since you bored it out to 89.5mm you would need a hg .5 bigger than that which would be the 90mm hg but 90.5mm should work id ask when you order your gasket or bore it out another .5mm
just trying to clear this up and help you out and give you the theory
