A buddy of mine did a compression test and determined it was the first three driver side . So I have to put the cams back in then check the clearance???
If you don't know the clearance numbers before he took the cam out then that's the only way to know. And if you are going to do that then make sure you check them all.

What's bad with the buckets?

Usually when those buckets go bad there's a little nipple inside that wears off and it causes the tapping noise, if the engine doesn't run the first thing you need to do is check fuel pressure if fuel pressure is good make sure you have fuel I've seen them where they were empty on fuel if you'll take is full then you need to do a compression test and a leak down test those buckets the picture that you showed looked okay to me

looks like an oiling issue to me.

the bucket is guided by the bore around the valve guide.

the markings on the side of the bucket suggests it's chattering.
