Great job getting out there and trying it. A few points to help in case I don't get to help you in person:
1) Yep, that's a 12 if you can get a 1.7 60' by not spinning. However, I was having trouble getting 1.7s at PMI even with tons of experience due to how slick the surface is on the street car side. You can do it, but it's not as easy as doing it at better tracks.
2) You have NOTHING to worry about in regards to the valvetrain if you shfit at redline. Redline is 7k, but our rev limiter is closer to 8k (7600 stock and 7800-8000 flashed). You don't continue making much power above 7k anyway, so you'll want to shift somewhere around 6600-7000 probably. Even if you were going to 8k, you don't need an upgraded valvetrain anyway.
3) Don't worry one bit about R/T, since it doesn't affect your run unless you're in an actual competition (heads-up or bracket).
