The only way that I know of is to have the dealer hook up to it to find out if it's stock or not. As far as head studs go. Look just below valve cover at the bottom is there a big bolt head sticking out (something like a 20mm) or is it a stud with a 12 point type nut on it. If it's the later then you have head studs. If not you have the factory TTY bolts. I will see if I can dig up pics of it. They have posted many times.
