not true. if you test the materials on these things, you'll find that
there are deep and fundamental differences that determine the potential
of a vehicle to last. crappy liners and crappy rings will never get
there. same with cheapo cams and followers - soft metal ground with
poor precision is just not capable of lasting. they'll both get you to
100k, and the cheap one, with anal maintenance maybe 300k, but a
million? never.
take the head off a 100k frod and feel the ridge on the liner where the
rings top out because the metal has worn away. this is a known wear
rate, and the tolerances on the rings are such that the projected
mileage is determined by how much ring/liner is left. just like wear on
a brake pad. take the head off the same mileage 1990 honda and not only
is there no ridge, it's still got the original cross-hatching on it.
that is a /significantly/ different wear rate. you can see this in oil
analysis numbers with the iron content too.
bottom line, only a few vehicles are built such that they can get to a
million miles, and it costs money to do that. that expenditure is not
considered "a good investment in building brand loyalty" these days.

most unlikely. honda have been cutting back on things like transmission
longevity, so it is most unlikely they're not also cutting back on
engine longevity too. it's part of the reason to move to cam chains
instead of belts - belts presume scheduled changes and continuing
operation. chains are "lasts the life of the engine", which is code for
"we've pre-determined the life, so you'd be wasting your time".
