Found an old thread that suggests my lunati springs are the same as PAC 1218.

I would check about 15k and just pull a couple off both intake and exhaust. If the seat pressures are good, throw them back on. That will at least give you an idea on how they are wearing. If they are still strong, check them in another 10k or so and go from there.
