If a blade is 8/8 or 4/8 with the proper geometry the bevel angles will be the same/similar. Adding a layer of tape to either will alter the bevel angle the same amount which is very little. IIRC about 1/2 a degree in either case.

Be careful with taping a 4/8 or smaller blade. If one side of the tape is further down the blade than the other, not centered on the spine, you may be riding on the bottom edge of the lower tape's side and not the spine. The heavier the grind the more careful you have to be. This has happened to me.
