Before I did our heads I got bottles of this stuff to give it a try. The
local subaru dealer had it in stock and it was real cheap ($2-$3?). A lot
of people use 2 bottles. Definitely worth a shot! Didn't work for me
though. My leak was *really* slow---a drop or two a night, unless it was
really cold, in which case I got I small puddle underneath. When I did the
heads, the gaskets and head mating surfaces were in horrible shape. I would
try the subaru stuff to hold you over, but do the job right before taking
any big trips (I did it to get ready for our 8000 mile cross country trip).
For what it's worth, the rebuilt heads are generally frowned upon.
Supposedly the welding actually stresses the metal and makes them more
likely to develop problematic cracks---so that putting your old heads back
on might even be better. If you want to do that, you should take them to a
machine shop who can pressure test them and resurface them. Otherwise buy
the new AMC heads if you can afford it.
Things that can go wrong: the cylinder sleeves can be stuck in the heads to
where they are realliy difficult to separate. Sometimes this means you have
to pull them out with the heads to get them off. (With mine, they were
still a major pain to remove on the bench.) If this happens, you have the
problem of getting them back on (getting the pistons back in the
cylinders). At this point, I think the best thing to do is remove the
pistons, and have them properly soak-cleaned by a machine shop (no
scraping/scratching of the ring grooves) and put on new rings (also need to
rehone the cylinders). All of this can be done with the engine still in the
van but it's not pretty. Hopefully you can break your cylinders free in
which case you don't have to go this route.
I've only done the job once, and I could have comfortably had it done in a
weekend if I didn't have to pull out the cylinders. It was a week before I
got it all back together including running around to the machine shop and
waiting for things I needed.
Good luck!
