You can check the valve opening angle by using a leakdown tester which
injects low-pressure air into a cylinder as you rotate the engine and listen
to the intake plenum with a stethoscope. There is a spec in the book for
intake opening angle - you check the TDC mark against the timing scale at
the place you first hear air coming out the intake. Useful for checking
flattened camshafts or the problem you suspect.
Also - the wiring harness? Has it been thoroughly checked from the ECU to
all the terminals? Did your guy have KNOWN GOOD components to work with when
replacing parts? Like from a perfectly running vehicle? (new is NOT the same
as KNOWN GOOD.)

The propane tank doesn't usually get hauled around without the car - it's
bolted in. It's true the buggers always want a "minimum" amount to fill the
tank in the SF Bay area, but one can simply drive out of town a ways and
have it filled by civilized humans. There's no minimum in Arcata, or even
Ukiah (at least not the last time I got propane there). Then, remember to
have it filled before returning home and then it's full before you go the
next time, and you don't even have to remember to stop on your way out of
town.

It can't really be done properly without serious metal fabrication. The
roofs of the two types are fundamentally different. The poptop opening is a
rolled back edge that provide reinforcement to stiffen the box-structure of
the van, which otherwise would be sacrificed. Cutting a big hole in the top
would remove several of the lateral channels across the roof. These are not
for decoration...

You're a step ahead of me, then - I have only done a few extemporaneous
fiberglass repairs, and never had to be concerned with appearances.
Have fun - looks like you're in for an enjoyable afternoon or two!
