Yes! Your brain gets programmed to hearing the "chug chug chug" that is perfectly timed with the shakes. Now the "chug" part is gone and I'm left with just the shake.
What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I had my air compressor set to 90 psi and was good to go. Once you pull all of your rockers give the retainers a nice bump with a non-metallic deadblow
Yup got them in, finished the job on Saturday............damn its nice to go beyond 5000rpm now.
Intake valve spring on #2 was broken (primary spring)
Exhaust valve spring on #4 was broken (secondary spring)
Intake valve spring on #8 was broken/collapsed (primary spring)
I was no shit maybe 2 minutes of engine run time before the #8 intake valve would have dropped. So gents........listen to your gut.
I will get some pictures up later.

Were they just lousy springs? That def would've sucked. I had a ruined motor because a sprung broke and dropped a valve.

Those were new, correct?
No shit, after I got done I bought some Mega Millions and Powerball ticket.......glad to see we all think alike.
The PAC springs were new with the cylinder heads I bought for the build. I sent the pictures to the guy I bought the heads from........we had an adult conversation and he covered the cost of my new BTR spring set.....so I was happy.
Sucks I had to do it, but way better then what could have happened. I knew something was not right and went with my gut......so glad I did.
So yeah, Luck with sprinkles of experience
