Did you have the crank bores in the rods redone, or just use them as is...
I get new rod bolts and have the crank bores of the rods remachined after installing the new bolts, that way the cap and rod are properly aligned and the bores are fresh and round to spec...
You need to make sure not to torque the rod bolts too much - 5 times max, to prevent stretching them too much and weakening them...
