No way you get to 520 with just the kit. Add a cam and maybe. The flow numbers on the heads do not appear to be on par with most decent aftermarket heads. I have to admit that I didn't pay attention to the lift. Looks like sketchy advertising considering they said on a "well built" LS engine. That likely means big cam and elevated compression along with some others. Just a guess though as they were pretty vague.

 

IMO, that Typhoon intake is cheap china junk. Just because it's got a 90mm TB doesn't mean it's a good intake..
Prolly stock 243 heads and cheap crane rockers. May see 380rw out of it without a cam. Cam only will get you to about 400rw. Good an't cheap and cheap an't always that good.

 

If it sounds too good to be true...
