While flying my Raptor 60 in FFF, I have noticed that it pitches nose-down when I input left cyclic and nose-up when I input right. Is this normal?

No it's not normal and there are three possible explanations coming into my mind.

1. Check if you have any aile-elevator mix engaged in your radio.

2. If you have the stock plastic head then you are giving a tiny elevator input. Try using some expo in your cyclics. This should help.

3. If you have an upgraded head with adjustable phase then you might have a wrong mix in your phase.

It could also just be your paddles. In forward flight with my R90 with the White MA Paddles, it was very twitchy. When I put on the V- Paddles, that took away from the pitchiness.

I also hear that if you shave down a few cm from the leading edge with the white MA paddles, that eliminates some of the pitchiness.

I have no mixes enabled and I'm pretty sure that I'm not inadvertently putting in any elevator with aileron (I'm a 20 year veteran of planks and have a very good sense of what my thumbs are doing). It only happens in fast foward flight. I know that my servos are correct (again, I've been at R/C for 20 years, 8 in helis). Any other suggestions?

Check your wash-out base if there is play in it this will cause the pitchiness your talking about. Take your paddle and lightly twist the paddle and watch the wash-out base if there is movement replace the base and make sure all links are slop free as well. If you are using MA white paddles put a big nice rounded leading edge and this will help but they will still tend to pitchie in fast forward flight.

COG? Too far back will cause that also.
