The head porter is a reputable Mopar guy who makes his living doing heads so I put some weight I what he says. He does sell a competing aluminum head but I don't get that vibe from him that he would stear me away from the stealth to sell his stuff. I have looked back through the form and saw some posts about the stealths being soft and some cracking issues a bit before the time I bought my heads so I got nervous. I didn't see anything about dropping seats though. I originally planned to just port the stealths and feel a bit more confident about it now if that is everyones recommendation. AndyF you say to sell the Indy for a RPM? I thought the Indy was a better flowing intake? Running a hydraulic roller cam around 250 @ .50 How frequent are spring changes, lifter rebuids etc for the hydraulic rollers? I thought the sft cam would be easier to maintain and easier on parts but am all ears! I appreciate it!
