Forget HP limits.
RPM kills rods.

The typical rod failure happens at the top of the exhaust stroke when the crank rips the rod away from the piston.

Compressive failures like bent rods are usually tune related.

Other failures come from rod bolts or bearings but in those cases the rod is just another victim.

In the grand scheme of things is your engine worth the cost of good rods?
