A buddy of mine is helping me put a crank in my 6.2L. I told him to hold up on putting the crank in because I was going to try to get new main bearing cap bolts. Are the main bearing cap bolts on 6.2Ls torque-to-yield (one time use) bolts? I know the head bolts are TTY, but I hear conflicting stories as to whether the main bolts are or not. If they are, is GM the only place I can get new ones? The local GM dealer says that they can only locate 6 of the inner bolts and 1 of the outers (or vice versa). I called ARP and they don't make them for the 6.2L. Can I safely reuse the old main bolts?

Thanks.
