Quick update, spent a few hours this weekend getting the heads off to inspect the damage. The biggest pain was the removing the rear crossover pipe and the drives side oxygen sensor. Luckily, all of the head bolts came out without any snapping. Here is a picture of the passenger bank, no obvious head gasket breaches but you can clearly see the center two cylinders have had coolant in the combustion chambers:
Where as the drivers side cylinder heads are as I would expect to see them:
Next step is to make sure there is no warping on the block mating surfaces, if this checks out then she’s going to be saved, I’ll be sending the heads to the machine shop this afternoon.
The passenger exhaust cam timing was off so I was expecting some contact between those valves and the cylinder heads and that was obvious on the last cylinder, the machine shop will assess the damage to see if anything is bent and requiring replacement.
