Running hot after partial coolant change

Okay. Let it idle in the driveway for a bit, the coolant level rose slightly several times and flowed into the reservoir, temp held exactly at 190. Decided to shut it down and attempt to diagnose the ticking/dead cylinder. While I was waiting for it to cool a bit, decided to squeeze the upper rad hose. Burped out some air, but more interestingly, a chunk of material appeared. After some fishing, I tweezed out a piece of black RTV that must have dislodged itself from the intake. Maybe that was restricting the flow through the thermostat, and by squeezing repeatedly I got it to flow through into the radiator?

Anyhow, on to the tick. Removed the driver side valve cover an BAM. Right away I found a collapsed #1 intake lifter. Hopefully that is all that is wrong.
