I have an 02' Z and I am about to get new heads, cam, and headers. I already have a intake and catback exhaust plus a TNT 150 shot. I have seen posts that say certain setups are not good for nitrous. What is the best head/cam setup to spray on? Also who makes the best headers? I want to acheive 600rwhp on the juice, so which heads/cams will produce 450rwhp N/A and be best suited for nitrous? and where would be the best place to get them? Thanks for all your help in advance.
