I guess it would depend on how much time and money you got. AND how bad you want to break the motor down. Before I went crazy and started tearing stuff apart I'd get a set of headers, a better intake and top that w/ a holley 650DP, then try a set of 1.6 roller rockers. As mention advance it some more. And you really should step up to 3.55's unless you do a ton of hwy driving.
