Top end is torn down and 99% good news. Two issues that might not be real issues:

Intake cam has what appears to be old surface rust between the two lobes on cylinder 1 (assuming they are numbered from the "front" to the back) while all other areas have normal oil or varnish.

Slightly uneven carbon deposits on the exhaust valves with shiny bits in the carbon on cylinder 2.

I am assuming the first one is likely condensation. In my experience the second can only be detonation or foreign object ingestion, but I am open to suggestions.

Head gasket was Volvo. Timing belt was Volvo. Water pump was perfect as were both the idler and tensioner.

Another unexpected set of findings:

Tiny bit of what looks all the world like orange RTV on the cam cover bolt holes (both cover and head).

6-point "standard" head bolts for the head bolts.

What type of keeper is used on the valve spring retainers? The stem seals do need replaced and want to make sure I have everything.
