No. You will need dual springs to handle anything over .600
I think ZO6 springs are camparable or a step behind the Comp 918's which are only good to around .600 I think the Patriot dual golds are gonna be your best bet for that much lift.
I know you saw the discusion about that crazy lift in the previous thread so I won't comment on it.

Z06 springs are rated to .570 lift by GM, though some people have been known to push them to near .600 lift. It lowers the RPM limit due to loss of control and shortens the spring life by a bunch though...

man, seriously, I don't care if you got that cam for free.....sell it. You are going to spend $200 in valve springs which aren't going to last very long anyways so in time it's not going to be any cheaper(or better).

Just get a nice tr220 on .551 lift and use some ls6 springs. It will save you TONS of headaches down the road.
