I have a 1995 cobra that is stock outside of exhaust and a msd billet dizzy. It also has a Procharger p600b with an intercooler that I have yet to run. I am trying to make up my mind on cylinder heads. Is it possible for me to make 450 rwh running the stock gt40 heads, and the stock cobra cam with the right dyno tune? If not, what would be the easiest way to get there? I would like to push 10 pounds of boost. Should I pull the motor and install a main stud girdle? Should I stud the heads as well?
