Your thread is a really good one, but didn't remember seeing much on the micrometer.

Got the headstuds done on the driver's side. Had to rock it to get the two rear most studs in. Had to move the power steering pump for the very front one.

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 *****.

Drivers side is done. Took .045 at every valve, so not too bad. I think if I have to do this again I will pull the motor.

Lol yep the passenger side ought to be a real treat I'm sure. Sucks you had to do it twice. The new motor is holding up pretty good though yeah?

Good deal, I am curious how you will feel the difference in RPM capacity.

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.
