The engine below used stock 289 rods that had ARP bolts installed. No polishing. Just good bolts and good machine work.

They saw close to 7000 rpm pretty much every time the car came out of the garage. When it went to the track, it went through dozens of nitrous bottles 200hp at a time at those rpms.

No problem. The rods are stronger than the crank and block.

Good Luck!
