I would like to mention a couple of things.
First of all, there are probably 10 bazillion Chevy motors runing around with the bypass still working and no damage to the motor.
I know of 2 engines that were pretty well destroyed due to an oil filter coming apart internally and the filter material ending up in the main oil feed to the motor. Both these engines had the bypass blocked.
Moral to the story...I personally would not block the bypass on anything but an all out, race only, engine. If you still decide to keep it blocked, make certain that you run only the very best HP type oil filters...either Fram HP series or Moroso. And always warm the engine up completely to operating temp before any type of rpm's are attempted.
In my opinion, its not worth the possible damage to an engine. Most of us change our oil before it even gets dirty anyway, so who cares ???
