Thanks for the input. Like I said, its been running great since I put the head back on and everything back together. Its not a matter of knowing what is in there, I do know what is in there. Metal. I don't see a real purpose in pulling the head, as it was just pulled when it went out for disassembly and cleaning, as well as the cams.
I feel the head is okay. The scoring happened when the lifter ruptured and material circulated within the head. The oil filter is trapping particles that will enter the head, so I am not worried about metal entering the head. I cannot see how if the oil filter is functioning properly, which it likely is as it is a Mahle filter, the head is getting damaged. If the filter is doing its job the head should be fine.
With that being said, most of the pieces are probably in the bottom end doing some work down there. If I'm going to drop the pan, I'd rather remove the engine completely. I don't have a hoist, and I'd rather just pull the engine out the top, put it on a stand, and work on it in the comfort of a chair.

Living with a Porsche 944: Engine out the top - Easy Peasy
He did it pretty easy, much easier then lying on my back trying to align the pan and all that junk. I could do a more thorough and complete job with the engine out. I'd probably leave the head on, maybe remove the cams and learn how to dial them in myself with some dial gauges, because it would be a good opportunity to learn.
I also need to change the clutch, and it can be done with the engine out. I can kill two birds with one rather large expensive stone.At least, that was my line of thinking.
