This is the before and after picture, each adjusted to be as far away from the spec limits as i could:
Intake
1- 0.23->0.19
2- 0.19
3- 0.22
4- 0.22
5- 0.23->0.19
6- 0.22
7- 0.23->0.19
8- 0.23->0.19
9- 0.23->0.19
10- 0.20
11- 0.23->0.19
12- 0.21
Exhaust
1- 0.26->0.30
2- 0.29
3- 0.30
4- 0.29
5- 0.29
6- 0.28->0.31
7- 0.31
8- 0.30
9- 0.29
10- 0.29
11- 0.29
12- 0.28->0.32
Only one valve was out of spec (exhaust valve 1).
I may have just had most of the intake valves adjust to the top of the limit and the exhaust valves adjusted to the bottom of the limit by the dealer at Inspection I, but the engine is somewhat smoother and slightly quieter now.
