I probably purchased whatever the other chaps recommend. Using the mic is the only way to do the springs as far as I am concerned. My truck revs SO much better it is not funny. Definitely takes a bit of math to have the springs at the correct installed height...No8 was a real *****.

Im pretty curious as well. Just put in 238/100 injectors a couple weeks ago, and while detuned it made a huge difference. Pretty happy every cylinder took .045 of shims.

What did your installed height end up at with the seal installed? Assuming you're doing Comp 910s? I like 1.750" for 910s, but up to 1.780 is fine for most below 55psi boost/drive pressure. You shouldn't notice much from the springs aside from it wont bend pushrods or break rockers everytime you try to play around with it if they're set up correctly.
