Yes they are.. Just make sure when you press on the pedal that the voltage numbers increase nice and smooth, not jumping around.

What engine is your "496"? What computer do you have controlling it? What the TPS sensor should read will vary, depending on the computer/engine. Your numbers are correct for an LT1, but I don't see any LT1 engine in your signature?
