Stock bolts have a torque spec of 42 ft lb with oil. ARP are only about $60 and you torque them to 50 with the super slippery ARP grease. ARP are around 50 % stronger, a good upgrade so long as you get the big ends refinished with them installed.

Yes, when you change to ARP bolts it is a very good idea to have the rods big end resized. The clamping power of the ARP bolt is so much better. You also need to do the same when you change to ARP main brg studs.
