Burning oil after new head install

[IrishKW]

I pulled the valve cover and see these supposed to be new rocker arms, they told me they changed them all but the Jake. Don't look to good to me for only 18,000 miles​.   

I ran the bubble test again to make sure what injector was bad, I necked down the tube as in Rawze's video, that works very well. Both 1&2 put out a lot of bubbles, 3 had just a few, none on 4 thru 6. Pulled 1&2 debating on whether or not to do 3.

Took a light a looked in down the cups, #1 looks like it is grianey on top almost like sand, 2 looks nice and smooth. This picture is of #1   

The injectors I pulled are 4088725, according to quickserve my CPL calls for 4088665. Do I need to change them all to what the CPL calls ​for? Or just get a couple like I have?

I haven't made any discovery to the cause of my oil usage yet.
I'll pull the exhaust manifold to see if I can see any oil this weekend if I get time
