Well, they may actually drop right in, but how much lift you can run on them will change drastically. You'll have to check your install height, then coilbind, then subtract the two, and then subtract another 50thou and that'll be your max lift with those springs. You'll also want to check your pressures to make sure they'll be enough.

Don't think it'll work, just measured one up....
Most LS1 heads installed height is 1.775", th the pressure is 170 with these LS7 springs.
It also coil binds at 1.300 so you'll need a 1.950 installed height to work for .600 lift. At 1.250 open its less then 350lbs, not enough!
