I haven't hoisted an inline 6 but have V8 many times. A chain works great.
I've connected the chain to an intake manifold bolt - replaced it with a
longer one.

You can pull the engine and tranny together or separate. Together usually
has problems trying to get the engine over the rad frame and the tranny
jams at the firewall. The engine/tranny has to tilt at quite an angle. You
can buy a hoist accessory that will allow you to keep the engine level or
tilt it.

Have you tried Inliners International at http://www.inliners.org? They
specialize in inline 6s - typically stovebolts like yours.

The six in my old '74 Nova had a pair of lifting rings on it. One bolted
to the head on the rear near the firewall and the other one was on the
front of the head.

Don't have to use a head bolt just bolt the chain to a couple of the
empty holes in the head.
You can pull everything together BUT it isn't light. Make sure you have
a place to put it.

Chain works fine, but I highly recommend an engine tilter, especially if
you're doing the combined engine/trans.  If you scrounge around some
boneyards, you should be able to find some factory hoist loops - bolted to
the intake at opposite corners.

If you're pulling it with the trans, drop the driveshaft at the rear yoke
first, then pull the drive yoke out of the tailhousing.  Pick up a plug for
the tranny tailshaft (or a spare splined yoke from a boneyard) or you'll end
up draining the trans all over the floor when the combo's tilted.

Check, double-check, then triple-check that all hoses, speedo cable, ground
straps, exhaust, wiring, tranny linkage, etc. are all disconnected before
undoing the engine and tranny mounts - nothing worse than getting the engine
up 3-4" and having it hang on something still connected.  While you're
jacking it out, if you encounter any resistance, stop and check it out to
see what's hanging. I once saw a guy destroy a vintage shift linkage because
he just kept going.......

Chains are fine.  My buddy and I have been using the same chain forever
on our project cars.  Combined weight of your engine and trans is
probably around 600-800 pounds.  Not sure how much the 6 weighs, but my
crate smallblock was 450 pounds and a TH350 is about 150-200 pounds when
 full of fluid.  I've never weighed a manual trans either...

Like the other guys said, find the factory lift points - they'll look
like a piece of bar stock with a 3/4" hole or something bolted to each
side of the engine.  If not, you can use a headbolt, but I'd probably
use a bellhousing bolt and an accessory drive bolt instead.
If you want to pull the engine and trans together, you might need to
remove the hood to get enough clearance.

My biggest tip:  Don't rush.  Especially if it's the first time.
Disconnect everything, and then check again.  On an old Nova like yours
there's not that much stuff to disconnect, but there's still lots - fuel
lines, shift linkages, etc.

Also, you'll need the car up in the air to disconnect the driveshaft and
stuff, but make sure it's not too high - or you might find the oil pan
doesn't want to clear the radiator.

It's also hard to have too many helpers for this.  Even if they're just
an extra set of eyes.

Oh... and never stand on the cowl to guide the transmission out.  My
buddy had to buy a new windshield for his Nova after putting his behind
through it.

All good advice... I might suggest pull the radiator out before removing the
engine, Since you have to remove the hoses anyway it's just a mater of a few
bolts, better than having to by a new radiator
