they'll be fine. i used the same spring to rev my 5.3 with a 216/224 .551 to 6400 and i also use a set to rev my new 5.3 with a 212/218 .522/.529 to 6400...and i'll prolly use a set to rev my turbo'd 5.3 to 6200...
the yellow zo6 springs are good for .570" max lift right?
Yup. They will be fine. Just make sure to give the motor proper warm up time before rapping it up past 3K RPMS. Those springs are a little more brittle than 918s... You might get some extra valve train clatter, but hopefully your exhaust will drown that out :)
well the guy at sdpc said the 918's have been crap lately and they sent every set they had back. so if the zo6 yellows will be fine and they are over 100 dollars cheaper, then great!
Just happen to see where they (Comp) are replacing the 918 with 928 , something about a free swap out if you have the 918 .
