Dealership wants 20 bucks a pop. Where is a cheap place online i can snag some?

Also, what clearances should i set them up at? Oem specs?

This is on a turbo tracked 8.5:1 motor with supertech valves/springs.

 

If the cam is stock, go with oem. If it is not, go with what the cam company specs.

I have heard of Spec Miata Racers going just a tad tighter to get more lift and duration. I have no idea how tight that would be however.
