What a _wonderful_ day. My ghia attempted suicide. 15 miles
between jobs, and suddenly i'm trailing smoke like a stricken
fighter. Even the passenger compartment had clouds of smoke.

Pulled over, realized damage was done, continued on on 3
cylinders, with people behind me seriously irritated

This car was bought by my grandmother, for my son; everything is
a surprise. Engine pull revealed 92x69mm. The dual-port had not
swallowed a valve, as I had thought, but sucked a valve guide
out of the head. Unfortunately, part of the guide made it into
the cylinder, leaving the head and the piston crown, shall we
say, sparkly.

Now I'm in a huge bind. What should I do? Jeez! Has anyone
looked at the price of heads these days?

Not knowing what heads these are, can I safely get only one
(matching valve sizes, of course).

Should I just get a valve guide?

OK - I'm a licensed aircraft mechanic, and I'm not stupid (or
maybe just slightly) but, at the moment, I'm seriously limited
on cash! I'm saving every dime to get my wife and kids here.

Correct: Replace both heads, and all 4 barrel/pistons

OK: Match head, replace cylinder/piston

Desperate: Stick a new guide in a hole that has proven unable to
retain a guide, and hope that the battered metal in the
combustion chamber doesn't create pre-ignition hotspots.

All opinions are welcomed.

TIA guys.

Lemme go cry now
