Injectors - Heads/Cam... needed?
It seems that 1 out of 10 people/shops that I checked with recommended new injectors with a Heads/Cam setup. It seems it's not necessary or needed.
Thoughts?

An over-worked injector can fail very easily and take a piston with it. Get some SVO 30#, tune them, and no more worries!

Yep my tuner says the same. H/C pushes them to their limit and he claims that they become unstable at that 90 + of their duty cycle.
They recomend 38 lb for this application stock Z06 is 24 I believe.

Now the question becomes whether the Tuner may be trying to sell something that's not necesarily needed, but makes them more money (obviously no offense meant here).
As far as the '02 maxing out stock, that's something I've never heard. There has to be something else goofy going on there.
I think you have to go with who you trust, and the "Big Names" I called, only one said it would be "good to do" for this setup.

Is there a noticed reduction in fuel economy with the better flowing injectors ? I suspect that would be the compromise and could be why chevy engineers may not have gone the extra mile on the injectors ... just a WAG on my part.
BTW .... I am a newbie Vette owner ... Just curious about how such mods may effect fuel economy really. My Z is my daily commuter and I likely wont be tracking it at all (maybe once to get the experience), so I dont really have intentions of modding to this degree.

I have a used set of BLUE PRINTED (I have the build sheet in the box, they flow indentically, like lab equipment) SVO #30's laying around. They do work better, tested them at Thunderhill and on the road, before and after with my MTI heads and Cam package.
I have my friends son selling them for me, as of yesterday. I think I paid $650 for them. How about $300+$10 to ship? According to the guy that put the top end together on my motor, I had to move up to #36's in combination with the Walbro pump to feed the new 429.
