Your drive train should be fine, intake and exhaust upgrade will definitely help with power gains. I fixed the heads/headers/tune at first and was around 500 rwhp, later I added the MSD intake and BTR stage 2 cam, I am currently at 545 rwhp. The BTR stage 2 drives nice, I don't feel like I gave up much drivability, it's a mild cam. I hope that helps...

I'm in Calif too and considering same. Where do you source 95 octane?
Also, I run A Street in my stock 2012 Z06 for Auto X. I see you are CAM S. What are differences?
Many speed shops and fuel depots sell 5 gal cans, you have to look/call. Without a tune you are wasting $$$. CAM you can do almost any mod but 200tw, Street you can do almost nothing plus 200tw tires. WAY over simplified, read the rules.
But to keep things friendly, I would recommend a small to mild cam (Cam Motion LS7 Stage 2) and having your factory heads ported (Advanced Induction) and the tolerances checked. Then a good dyno tune.
If you want to get a little more power out of it and more sound, a set of quality headers (Kooks or American Racing) would also be good.
I would skip adding any aftermarket intake as there really isn't much to gain considering the cost. But a shroud over the factory intake would help.

It just basically isolates the air intake from sucking in hot air from the engine bay so that power remains consistent. A lot of people also combine this with cutting the factory radiator shroud to allow more cool air to get to the front of the intake.
Here is a Haltech Beehive shroud that I had modified to fit the intake on my Grand Sport:
I like the Haltech shroud as it has a clean factory look.
The only thing I made sure to do with my Z06 is upgrade to a twin disc clutch setup; however, I did manage to shred the rear end doing stupid stuff. For the clutch, I started with a twin carbon disc, but hated how it sounded, so I switched to the LS9X (this was before the LT1 clutches existed). My mod multi-year progression on my 2008 Z06 was roughly as follows:
CAI + Tune
^^ + Headers + Twin-disc Clutch (BC2)
^^ + RPM Stage 2 differential (shredded the stock one doing a clutch dump and burnout in front of my brother-in-laws house - a $3000 mistake)
^^ + Ported, shaved heads (higher compression) and stock intake
Changed to Fast LSX intake and ported throttle body
Changed to slightly milder cam to improve drivability (too much shaking - not wife friendly)
Had a cam lobe get eaten by a faulty lifter, and did a complete tear down and rebuild with all forged internals and slightly larger bore (new Ferrea valves, beehive springs, CHE rockers, link-bar lifters), ARE dry sump inserts, pan baffles, Katech oil pump, et. a
The thing about modding is it's never really done.
Give the guys a AHP a call and ask about their 116 CAM and tune. I have their 116 in my car with stock intake and exhaust with X pipe and cat back. I don't understand why you want a 95 Octane tune and are concerned with street friendly driving? Those don't seem to go together but to each his own. You can get most of it with pump gas but the tune is a must.

Well I will have BOTH tunes in the device, ez to switch tunes & gas in the tank?? Am I missing something/
Do your self a favor and call American heritage performance you won’t regret it I promise. They also have full CA legal setups that make 530-565whp smog passable

I can comment for a cam/intake/full exhaust C5Z with BTR Stage 2 and it's SUUUPER easy to drive on the street. My car is a dual purpose autocross toy/date night toy and DD and I made it clear that I want something that I can drive ANYWHERE and my wife can drive it...the BTR cam and custom tune delivers.
BTR Stage 2 cam
Dorman LS2 intake and LS2 TB
ATI 10% UD pulley
Full exhaust
stock clutch
ONLY time I get any bucking is very low RPM in 1st in a parking lot which sounds worse than it is. I can lug the car at 1000-1500 rpm in 3rd and no issues.
Only thing I would hold off on is maybe the heads to do them later if you want/need more power. But select the cam that works OK without heads now and works well WITH heads if you will do them later.

Should I do head/cam?
