Default 918s good for what lift?

Im gunna start gathering parts for my cam swap so when i get my LQ9 come income tax time i will have everything prepared, and i see "Z06dreaming" is selling his comp 918s for 100 bucks, so i wanted to know if they would be good enough for the cam im going with, it will either be a .581/.581 or .585/.585 lift on a 112lsa, so should the 918s be good enough? thx

918's are good to .600 lift, so you are good with those...

im pretty sure the 918's are underrated from the factory and they are actually good to .625 (they did this to up the sales of their 921's and 926 series)

That is odd maybe they chaged the design of them or something, I was told by USA Racing Engines in Houston about a year ago that I would have to change springs to go to a cam with over 600 lift due to coil bind. Either way they are good for 581 lift in question
