i got money to spend!!
well i was gonna say ranch hand but u already got one. how about some 1.7 roller rockers, fastman throttle body, and headers. might put you a little over but its close.
I agree with Motorbreath on the 1.7 rr's. They'll definitely help your truck. Then you can either go with the Fastman 50mm or a new cat-back exhaust system. The stock exhaust manifolds can be left alone till later as they are actually quit well designed. Without improving air intake (Fastman ,CAI, etc), engine (1.7 rr's) and exhaust (High Flow cat, cat back exhaust) new headers won't give you much improvement over stock.
