I might be able to pull a valve cover off this afternoon and put a vernier on one.

I use the nextek endurance spring Jamie, that's the one I was referring to... 200 lbs @ 2.00" IH I'd be inclined to suggest running whatever spring so that you're within .030" to .070" of coil bind so you won't have a spring surge issue to deal with... call me if you want more info
