Inliners International Forums General Discussion Engines reuse rod nuts, use locks ?

I'm preparing my 261 to replace the 235 that I removed from my 40 sedan.I am going to hone the cylinders and replace the rings and rod bearings. The bore is stock (standard), as are the rod journals. I'm wondering if I should reuse the rod nuts and/or use locks on the rod bolts. There were no locks on it from the factory. What say ye? thanks
