Also when people replace the bolts on the stock motor it usually already has a lot of miles on it anyway. People replace the bolts and then just assume 7k+ rpm's is going to be fine, even on the old stocker rods and bearings.

I can pretty much guarantee you that if you take a motor with some miles on it that has factory rod bolts and change them to either of these the rods will then be egg shaped. Even if you took a new set of rods that were sized with factory bolts and changed them they likely won't repeat. The bolts will be better but you run a greater risk of spinning a bearing. Some get away with it and some do not. I would not change them without a rebuild and doing it right.

Ive seen too many threads about people spinning rod bearings right after a rod bolt install to try it. My power curve tapers off at 6500 anyway, you must be running a big cam to need to spin that high.
