modracer33

I have an L33 going into a Mazda Miata. I am about install a 560 lift cam and got some Z06 springs for it.

But someone told me my springs were already Z06. I have the 799 head (same as the 243 Z06 head) my springs have teal colored stripe on them. Picture of the head and spring attached.

Can someone with experience in this give me a clue?

Thanks!
