I recently built a performance slant and used ARP head and main studs. I used studs as that engine is over 10:1 compression and has a host of other performance parts. The way studs apply clamp load without turning should improve integrity to the engine structure. With that said, I have never heard of an actual failure of an OE head or main bolt. As long as your bolts are not gouged or nicked or they should be fine to re use.
