And, yes in a perfect world having a tuner that knows that they are doing, an in car street tune is the best option.
What other mods are going to happen?? For an XP cam, don't you need stiffer springs in your heads or can you run stock?? I'd rather take the time to pull the motor to do the heads properly then keep it all in the car and work around everything. But that's my opinion.
