Battery was charged at 12V 1.25A (battery tender plus), battery itself is 12V 9A, sorry for the confusion. I think it's holding a charge now, left it off the charger all day yesterday and it only took a minute or two to get back to full. So good news.

Cam-timing results is the correct 33 pins:






Valve-clearances were really annoying to figure out. I just gave it a real good estimate with the lobe being as open as I could get it (the third pic), which was done by finding the point of engagement and disengagement of the lobe (the first two pics). Going by intake and exhaust on the last pic, that means at least 3/8 of them are out of spec and I should adjust 6/8 of them (so all except the labeled "3" intake valves). Valve adjusting screw locknuts is 17 Nm (aka 150in lb) from here. Used the guide here.
Quote:
The gap for the intake valves should be between 0.08mm and 0.13 mm
The page goes on to say that you want them on the loose end instead of the tight end.
Quote:
The gap for the exhaust valves should be between 0.11mm and 0.16mm






Also I found some red gunk through the sight hole, really not sure what it is.


And there was some coolant on top of the rear of the seal for the valve cover gasket.
