Get them L19 Head studs, lol.
Muckman, you think those LS rod bolts will be fine? I personally have no idea what their strength level is, but they are thin and I would just get ARP rod bolts for piece of mind if nothing else. They are cheap afterall. Also, if you plan on redoing your piston rings and are going to have the motor apart anyways then you might as well get upgraded hardware. If you do not plan on opening up the block then you might as well just run it until it blows. Then buy another block. LS blocks are cheap.
I agree though, why do you need a stage 3 clutch? Do you plan on launching the car a lot or something? Who are you having it built by?
