Previa In-Car Head Gasket Replacement - Will It Ever Run Again?

This is the most major auto repair-tainment I have attempted yet - my first ever Head Gasket replacement. At 297k miles, I am not really risking a lot by giving it a try at my own repair success - the 1994 Toyota Previa LE SC AllTrac has had a long and useful life as our family's beloved Floki, the Super Car Adventure Van.
I was only able to remove and install the new Head Gasket by following along to Sammay's UA-cam expert videos for his in-car engine lowered technique. Be sure to click over to the following UA-cam links for expert instruction if you are to pursue the Previa Head Gasket project on your own:

AGAIN, the above two UA-cam channel links are the EXPERTS. I am just auto repair-tainment and honestly, by the time you are seeing this my Previa head gasket replacement may very well have already failed...
So far so good though - I have now covered 125 miles including sustained highway driving 65-80 mph with no issues. But I am running through a full tank of gas before going for it all with the pedal to the floor - stay tuned.
