manual boost controller is fine, without the addition of an intercooler you'll get ping around 9 psi, with an intercooler you can run 13 psi from the stock turbo no problem, the headgasket and headlift become an issue as you approach 300 whp, which is more than you are likely to get from the stock turbo, with an aftermarket turbo you can lift the head and/or blow the headgasket which is why the headgasket and headstuds need to be upgraded, the stock head if fine and can take all the abuse you can throw at it, it does become a limiting factor around 400 whp, if your goal is 400 whp you need to plan on some port and cam work, and forged pistons for the bottom end
