Question: LS 7 Cam amd spring options

[C5NGAGE]

My 2007 C6 Z06 with its LS7 is getting some repairs.
Are there Chevy Performance Parts that make sense for this engine?
LS7 Stock Cam versus Stage II or Stage III cam ?
I wanted to use GM parts like the old days.
I had an L88 Cam in my 396 etc etc

Any guidance for updates would be great or experience with these items.

LSX Solution

Just got off the phone with GM Perfromance Parts and Kelly refered me to the LSX cam specs for a different option to the LS7 Upgrade. with 110 overlap it would idle more friendly but at .648 life we will need special springs. Chevy does not have any but they pointed me to PAC 1500 which are in Summit and Jegs. My question now is should I drop the 1.8 rocker ratio to a more sedate 1.7 or not. And the valve to piston clearance i need to verify but we are learnign and maybe making progress.
