b16 with skunk 2 stage 1 cams

i have a b16a with cai, headers clutch, vafc, and i wanted to know roughly how much horsepower would a good set of cams like skunk 2 stage 1 cams give me. roughly whats the range of hp im looking at. becaseu im not sure i want to spend that much money if its not gonna be a huge difference

my friend has the same setup in his 91 rs and hes getting 168 hp to the wheels after the cams. and i forgot what the torque is. I hope this helps.
