If you want to keep your motor N/A I would go with a nice top end kit (trickflow, Edelbrock, AFR) along with upgrading your Rocker Arms, Throttle Body, MAF, Fuel injectors , headers and exhaust!
This is what I did and going from stock dyno numbers (185rwhp) till now I gained 125 rwhp and dynoed at 310rwhp
