High Volume Fuel Pump?
I've been seeing high volume fuel pumps on the market, but I haven't seen them mentioned much around hear. Is this an important mod in order for a heads/cam LT1 with LT's to see maximum power? If so, would higher flowing injectors also be required?

I would add a high-flow fuelpump on any mildly modified car.
Heck when I put it on my stock '85 years ago, I felt a difference right away. (And the old one was not showing any problems, just upgraded in leu of new planned mods)..
i will be putting one in my stock '92 asap.

i added a 255Lph high vol. fuel pump out of pure fear.
i replaced my stock unit with an unnecessary HV one and paid a few dollars more in the process (about $20). i'm almost certain its meaningless, as CFI-EFI says, but i got some other fuel pump-related items in a kit that made it a 1-1 tradeoff in cost.
the rubber meets the road right at the fuel pressure regulator. in a 450chp
or less car, you probably don't need a wacked-up 255Lph unit. the FP regulator controls the final pressure, where it matters.
p.s. my next 400chp vette gets 1 5/8" headers
