Default want cams and upgraded valvetrain but able to pass CA smog

I want a wider power band. I'll be getting AVO's gt3076r jdm twinscroll turbo. I've read it's the nature of twinscroll turbos can pruduce a wide powerband. To further help this I'm debating on doing cams, springs and retainers. Would 272 cams pass smog?

if looking for a broader power band, skip the cams....

They simply move the power to the right, and further away from the left, which is opposite to what you appear to be trying to achieve...
