Default ls1 motor with ls6 style heads?

ok...this may have been asked before, but i read an article in car craft where they took a bone stock ls1, bolted some cnc'd ls6 heads, a fast 90mm intake and throttle body, comp springs and pushrods, and a crane zcam and kooks 1 3/4 headers and it made like 500 horse...anyone done this or seen results like this??

CNC'd heads from thunder states fifty over regular LS6 heads, so its believeable if you try real hard.

cam they used was a crane HR228 zcam...they are stating that all you need to make 500 horse out of an ls1 is a heads that flow 315 cfm and a cam slightly bigger than stock with the proper bolt ons....car craft november 2006 page 39
