spark plug gap

so I got into a del sol with a b18a1 from a 91 integra ls n a 91 gsr tranny.. I know its not a true integra.. the guy I got it from said it has slight internals done ready for low boost up to 7 or 8 lbs.. I decide to upgrade the plugs n wires.. so when I took off the plugs it has cyl1 at 39, cyl2 at 39, cyl3 at 47, n cyl4 at 44.. this is my first vehicles with a internally mod engine.. is this normal or just jacked up?
