do i need to buy the headgasket and new studs with it?

 

IMO: Common sense to replace gaskets (head to manifold and manifold to down pipe). Buy the studs for piece-of-mind -- that way you don't have to worry about breaking a stud and having to find another one -- just put the new studs on the new manifold and you're ready to go...

 

Although the rest of the car is a chopped up Z06, the engine itself isn't a blown LS7. Instead, GM is expected to use the all-aluminum 6.2-liter V8 currently found in the Cadillac Escalade. With more room between the cylinder walls than the LS7, the 6.2 is better suited to the extreme stresses associated with a supercharged engine. The 6.2 makes over 400 horsepower in standard trim, so breaking the 600 horsepower mark with the help of a blower shouldn't be a problem.
