I used Comp 918's when I had that cam.
Tit Rets. would be nice, but not necessary.
Do get hardened pushrods though.

It's not a must, but it's strongly recommended. When you compare the two next to each other you'll see why.

I'm using 918's and the "772" Ti retainers with a C1. 10K on the springs and so far, so good. I also am using the hardened pushrods.

The Crane duals are a drop in spring, no machining.

I'd say no matter what, go with a dual spring and stay away from the singles. There's another post befoer this one where a guy used those Comp 918's and the spring broke, wreaking havoc in the engine. With a dual spring you're almost always gonna have one spring to keep the valve up and save the motor from serious damage if you have a spring break. Plus, the duals have better harmonics for sustained RPM's and longevity.

There will be a couple of new valve springs introduced for the LS1/LS6 applications at the PRI show in December. A drop-in 1.260" made from ultra clean chrome silicon. Also a 1.480" spring for the high lift stuff. These engines will also benefit from the restrictor pushrod which helps in maintaining proper valve pressure in the lifter and promotes higher rpm.
