IF MY 80 Z-28 ONLY HAS 18000 ORIGINAL MILES, IS IT STILL NECESSARY TO INSTALL NEW VALVE SPRINGS OR PUSH RODS WHEN INSTALLING A MILD COMP HIGH ENERGY CAM?

THANKS.

With no more miles than that I would say you would not need to. Unless cam lift is more than .460 Much more is too much for stock springs.

Ditto. If you felt like it, you could get a new set of decent pushrods fairly cheap.

the car might only have 18,000 miles on it, but the car is also 23 years old. it couldn't hurt to pop in new valve springs.

I would personally used a new set of springs.

I always use the springs installed at the height that the cam manufacturer recommends. It will ensure the cam works the way it's supposed to.

Use what the cam manufacturer recommends - they know what it needs.

I'd say while you're doing it might as well. New springs aren't very much, and it may save you headaches later.
