Back to modding today. But two operations updates since I replaced my head gasket:

(1) Seems replacing the cam seal and redoing the valve cover seal has finally put an end to the persistent oil/fluids leaks I have been chasing for years.

(2) Car running great. I took her out for a couple hundred miles of driving for work/family so far since I finished the head gasket. Other than the p0420, no problems. And that CEL has not come back in 80 miles.

I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
