im putting together my spare sr20de+T and i wanted to get some info on my piston ring end gap. its stock replacement rings

my old ring gap
1st ring .015
2nd ring .021

new rings
1st ring .011
2nd ring .019

i checked the FSM and i noticed my new rings arent within standard spec.
is it ok to run the new rings at their current spec since the original rings were also way below standard spec? heres a piece from the FSM.
thanks for any help/advice
