how important is it to have this done. what i have is a z6 motor and a set of pm7 rods and pistons. i was told that i should have the rods shot peened. i have also had some people tell me that with what i will be running basic i/h/e that i won't need to have them shot peened. but i do drive a bit hard so i want to make sure that the motor stays together.

shot peening is just shooting little BB's at the rods and relieving stress, so to speak.

This along with heat treating and beam polishing is a good cheap combo to make your stock rods like new again, if not stronger.

It's not necessary....but it would be wise.
