You average is 127, which is low in general but could just be the gauge or crank speed
And I prefer 10%

Yes, you can WET test #6 but unless it comes up to 130 or higher it has a valve issue

Wet test on # 6 came back with 115. I immediately tested again and got 110.
 
Its a 2006 Ranger 3.0l so I would plan on replacing BOTH heads, they had a defect in the exhaust valve seats from 2004-2006

No, I don't have a specific brand name for these heads, someone may come back with that info
 
Update: My last mechanic said he had both heads sent to be machined in 2018. He doesn't think it's the valves, he said it's probably the rings or hydraulic lifters. Does this sound accurate?
 
Well, is the heads are only 2 years out from an overhaul then they aren't the top of my suspect list. Do a compression test, dry then wet, and see what happens.

Thanks. If you look a few responses back you will see the results of my dry test. The wet test showed a slight improvement in cylinder 6, but nothing significant
