no need to build it with the stock cams, because the car won't breathe at higher revs.
If you want to use stock cams, I'd suggest going with lighter valvetrain components, and REDUCING the spring rate to capture back lost horse, if you want to stick with stock cams that is.
No matter what you plan on doing, staying NA, or turboing later, I'd rip the head off, and do a lot of headwork. That will ALWAYS pay off, and you won't see your power dropping off as it currently does right now.
