More fun with Head gasket replacement!

So, im still not even sure thats the issue...but, we're this far in, so we're going to do the job anyway!
Valve cover is off...and here are some findings:
1. Timing chain looks sparkly new! Very (normal) tight all around, and appears to be tensioned correctly.
2. Oil feed tunes also appear to be seated correctly...so i dont suspect there to be any leaks there.
3. was told that pooled oil beneath the lower cam shaft is normal...so ill skip past that, but there is some oil pooled in the timing chain galley. Obviously gravity keeps it there, but how did it get there? Potentially caused by a Cyl 1 HG breach?
4. Are there any telltale signs of bad vale stem seals? This car had a smoke from dipstick condition, that we suspected could be caused by blowby from here...
Thoughts?
