Link doesn't work, but the Comp 850-16 lifters will work fine. The LS7 lifters are also a good, less expensive choice.

The 99893 springs will more than suffice.

those springs "should" work. if my math is correct those rockers put your lift at .570 and .578. couldnt get the link to work for the lifters, but the stockers should be ok with that set-up.

Yeah, as long as your stock lifters are ok, they will work fine. I have a CC503 and the Crane 10308 spring kit, with stock lifters in my '97 SS. But I am running Comp 1.6 ProMags. Tabbed 5.3 lift numbers are pretty much correct, I got .569"/.578", which AFAIK the Crane 10308 kit can handle. Don't know what your ideal installed height will be though. I went with 1.8" on my car.
