Just pull them out with pliers.
Here's the checkball to burp.
Now clean them with WD-40.
Burp and pump up, a couple of times to flush out the junk.
Now that they're clean, we will fill them with fresh oil. Squeeze the adjuster and open the ball. Don't release it yet.
Now release submerged in new oil. Purge, clean, and refill all eight of them.
Now check the tiny hole in the rockers. Make sure they all are clean.
Here we are washing again.
Oil the steel parts so they don't rust. A periodic correct oil can is the only way to do this.
Okay enough with the heads for now. What's with the ATF?
I was told by Hotsauce via The Judge that you can marinate the gaskets in ATF and they will stay where you put them during assembly and if you have to take things apart the gaskets won't stick and you can re-use them. Looks like a horror movie though.
We should be going up with this motor tomorrow!
