connecting rod question

The main thing on rods is how straight they are. They should not bend to the left or right or backwards or fowards. They should not look like there in the middle of a twist. (I feel like Dr. Suess) Big ends should be round and the like for the small ends.
If you allready put these into the engine, I'm guessing your machinest should have picked up a problem easy and told you about it, straightened it all out before he/she installed the pistons on the rods.
No news is good news.
Then theres balanceing the whole rotating assembly. It's worth the $300 (?) or so price and taking it back out to do it.

Otherwise, stock rod s will do fine and could use a shot peening and polish with good rod bolts to max them out. But, stock is fine.
