If set up exactly perfectly, they will just barely barely be enough. A very small error, and you'll wipe cam lobes.
I hope you really trust your head guy.

If its the 282hr cam likein your sig, why done you run the springs Comp recommends. THe 986-16's or the 987-16's. The 987's would seem, to me at least, to be the more preferable spring.

i didnt know what springs to run with it. i got the cam off a friend for 100$ but this is kinda a budget build and really cant afford nice springs... so thats why i was looking at the z28's..

is the cam in the engine? Is it possible to look at the rear of the cam, on the rear face, by the distributor gear? You will see the grind info there.
