What is the difference between a LS7 flywheel, clutch, & pressure plate, and the ones from a 4th gen LS1?

I am building a resleeved LS2 (440 ci) for road racing. I know it's a big engine for road racing but I will be able to get good power with a flatter power curve than a smaller engine. I'm planning on putting it into my 02 Z28 and backing it up with a T56. So I will need to purchase them as well as a few other items. I have seen several LS7 setups for sale so I was wondering it they would work for me and is there any advantage to the LS7 stuff.

Thanks

ls7 uses a stepped flywheel different pressure plate and a bigger disk to hold more power while still retaining a stock feel as a kit it bolts up fine to an ls1. the bad is that they still dont hold a bunch of power and the pressure plate design has the same flaws as the ls1/6 unit. also they're around 60lbs which is heavier than stock. I'd spend a little more coin and go with a good aftermarket setup

What kind of RWHP does the clutch need to support? Will it see any street duty, or just road race use?
