dont go by torque, torqueing them again and again weakens the bolt by over stretching it. The proper way is to check the rod bolt stretch anywhere from .005" to .008" even if its only like 40 ft lbs!

If you don't have the $200 stretch gauge (which most of us don't) it's 50 ft-lbs. I just put my new motor together with Eagle SIR's.
