I think everything you listed is fine. In fact, I kinda like it. You don't need headers. Have someone go through the Stealths. Cam is fine. TQ and factory intake is a good choice, but getting the TQ right might be a challenge. Buy the piston in your budget with a 2.06" compression height and you'll be good on CR. If your rockers are okay keep them, but this is a place that I like to upgrade.
