Help!! Ross 84.5mm piston ring gap.

Trying to put my engine together today after so many problems. Its a b18a and I had it sleeved. I bought custom ross pistons 84.5mm and it came with rings(I'm sure I paid for them for what I spent). I did a seach on here and came up with .020 for a gap on the first ring. I checked mine and am getting .032. The book (Haynes) says for stanard b20 its .0014 to .0024 which for 84mm. Plan on running up to 25psi. Had it bored .0045 over piston for gap. Pistons are 3.328 and the bore is 3.3325. I'll try to find out the brand the rings are.
