not to disrespect that setup, it will be very solid for you...but with more compression you would make more power, and be just as streetable. the spray would like a little higher compression also...just from my experience with SBC motors 11-12:1 are great streetable nitrous CRs...we just finished a 13.5:1 SBC with SB2.2 heads for our 84 Monte Carlo SS that will be seeing a bit of spray in it's future. good luck with your setup tho.
