Default cast piston ring gap

Just want to double check my numbers before I fit these tomarrow. I'm running a set of cast oem replacement 82mm pistons and will be eventually supercharging this engine. The equation I'm using is :

Top ring : .006 x 3.228" = .019" gap

Second ring : .0065 x 3.228" = .021" gap

got the equation from laskey racing's web site, just wanted to make sure they seem ok

i would probably go with oem spec if you're using cast pistons.

Thats kinda of what I figured but I think that the gaps have to be a little when the piston is bigger.
