...Waiting on the cam...
In the meantime, more cleaning. Focused on the intake manifold. Looks like my plan is working. Long soaks with occasional position changes. You can see the waterline on the top of the intake tube.
Couple more days and it should be clean as a whistle. For anyone wondering, this Sterilite container from Walmart is about the perfect size.
I think once the K10 is done and I tear back into the S10, I'll be doing this to that intake manifold as well. I got it kind of clean, but nowhere near as clean as this one will be.
