Impressed with the progress you're making AND time for the grandkids! Curious if there was any water in the intake tract downstream of the TB. I would think since TB was closed and tested to 26" manifold vacuum it should have been water tight. The exhaust side of course is open and 2 exhaust valve should be in various states of open but interesting they were same bank. As far as debris the catalyst is a pretty good strainer, so I wouldn't remove the headers unless you really want to. Since exhaust is stainless and water (condensation) is normal, The muffler is all I'd think that needs to be inspected. Carry On!!!
