I just had my block line bored for trueness, can I replace the standard main bolts w/ ARP bolts and not have it affect the line up of the caps?

Yes, but you need to fit the crank and check the clearances and that it rotates easily anyway.

Yeah that is ness. anyway I was just wondering if since the ARP bolts have a much higher torque rating, they might drive the crank journal closer to the bearing, thus throwing off the alighnment.......

Because of how studs work, there may be less, not more block distortion with the studs. The best way would be to align bore or hone with the studs, but the slightly different clamping loads of the studs shouldn't change anything, but check anyway as Rich said. Make sure you use APR's recommended procedure and lube when you assemble:

Your only using ARP bolts not studs. You should have no problem.

 

Changing from one brand of bolt to another should not cause a problem, as others indicated. If you're really concerned, then you could torque them to the same value as you used with the previous set of fasteners - anyone see a problem with that? I'd still recommend going with ARP's recommend torque and double-checking the bearing clearances - I really, really doubt that you'll have any problems.
