So it was running fine before you popped the head? Just wondering why you changed HG. Overheating, combustion gases in the rad, overfilling of the expansion tank, power loss, plugs carbonized, compression test, running rough, water in oil...
Who has more than 250k miles on original head gasket? (1 Viewer)

'94 with 285k miles, owned since ~253k. I have no reason to believe that my head gasket isn't original. Maybe I have the superior asbestos gasket. It worked for Popeye.
Dude...
His head gasket blew after an engine flush and he was reporting the damage he saw when he replaced it.

Stock gasket still holding strong when I pulled the engine at 280k mi to put a v8 in.
The head gasket was on the verge of failing and the flush took it over the edge.
272k 92 3FE
340k on what I believe to be the original gasket (can't say for sure, don't have complete maintenance history). No signs of imminent doom, but at this point I'm planning on pulling the motor to reseal everything (rear main leaks), valve job (burning a lot of oil), and will put in a brand spanking new head gasket at that time. The truck is still going strong, but my sense of mechanical empathy is telling me it's time for some R&R.

^^^ “mechanical empathy” 
I like that.
You drive something long enough, you can “feel” the subtleties of what the machine is doing internally. I think that is one of the most valuable abilities I learned growing up around mechanically minded folks. If you know how something is put together, and how the parts interact internally, you can often detect an imminent failure before it actually happens, or at least in the early stages.
Most folks will give you a blank look if you ask them to visualize what the various systems in the vehicle are doing at any given point. They just look for (and often miss) the warning light on the dashboard
