how sad it went bad in 1k miles. super sad.
he honed it , it would never need that with only 1k miles, ever,
3/4 low , smacks to me if only bad head gasket, or head and block not milled.
or cheap gaskets, not Felpro.
so let me be clear, engine was total engine rebuild 1,000 miles ago , head and block and is called a longblock rebuild, valve and seals rings and bore/ hone to fit new rings
and not 1000miles later rings failed, no way? no way that huge drop in PSI, never. (or ran out of oil or used 0w oil or some crazy oil additive snake oil there.
or OIL pressure at 5psi at 5000 RPM ,
ok Ive no clue why it failed, but head gasket failures are #1 and for sure , bad mill or wrong gasket used. (or wrong head torque, using inch lbs not foot /lbs and staging it per FSM.
many times with head pulled that gap between cylinder tears hiding the real cause, easy as pie.
ok new engine
do the FAM test,parked .
key on , 1.0–1.6 volts dc
idle hot, 1.7–2.0 volt dc
and gunned. it can hit 3vdc easy or more 4v be like super hard to hit unless flying up a large hill at full 95HP load on the engine.

your smog pages do not even hit of rich mixtures, that can wash oil off rings, hint hint.
I say only limphome mode can do that or FI pressure not 30s but 50s; with bad FPR valve.
just lean. and lean is HOT, very hot.
and too lean makes lots of NOX (egr works overtime correcting this)
