Straight off the book.
With engine in number one firing position
Tighten
1 - 2 - 7 - 8 exhaust rocker to 22ft lbs
1 - 3 - 4 - 5 intake rocker to 22ft lbs
Rotate engine 360*
Tighten
3 - 4 - 5 - 6 exhaust rocker to 22 ft lbs
2 - 6 - 7 - 8 intake rocker to 22 ft lbs.

When I did all that some I got 1/8 - 1/4 turn so obviously I messed up first time. I went back threw to 27ft/lbs and got a very consistent 1/4

Since engine was warm I decides to go to 30 ft lbs

Holding at 3500 in bay...sounds ok so far. Valve train all together sounds quieter

I spoke to soon. Returned after driving at 3500 in second gear for a bit to test.
I'm almost wondering exhaust noise? Any ideas?

Box they came in and invoice say "7.400 so no...not the size I ordered cause I ordered "7.425...maybe that's it?

7.4 isnt the right preload for the LS7 lifters.
7.425" is the ones you will need. That .025" is enough to cause valve train noise

Finally a dtc came up. Or cel.
P0171
Could that be detonation?

Po171 is lean code I would venture to say a tune possibly needs some tweaking if you havent had time to tweak it out yet
