changing springs well i did some searching and read that if i have a cam with XE-R lobes, then i should change my springs every 15k or so? is this accurate. my cam is a 224/230 112LSA with .567/572 lift. i have comp 918s on it and i put them in in july. i dont want my motor to pop on me, but dont want to get springs too early either

Then do the same for the open height. This is probably a lot more accurate than some spring testers I've seen.
