What are current day thoughts on head gasket coating? (none, plain
grease, copper coat grease or spray,nickel anti seize,etc?
The old man 60 years ago swore by grease as he was trained by the air
force.

Grease would be the very last thing I would put on a head gasket.
Unless you are talking about a head gasket for a very old engine then I
would put nothing on it because any "coating" that is needed is already
on the gasket as its supplied.
The most important thing is for both surfaces to be very clean and flat.

Grease would be one of the best things to use on any head gasket that you
*didn't* want to seal, as would any other non adhesive, non compressible
solid that's main purpose in life is to act as a lubricant.

I used to know an old guy, who was pretty old school, and he also swore by
grease for use on head gaskets. When I shook my head and asked him why, he
said "because it made the gaskets easy to remove". He used to be into
Valiants, and not surprisingly he used to go through head gaskets on a
pretty regular basis and could never put two and two together despite me and
a few other people telling him that the use of grease is what was actually
causing his problems.

Still, he was one of those guys who had his "ways", and couldn't be told.
His idea of a good valve job was to remove the head, take off the springs,
coat the underside of the valve head in heavy lapping paste and stick it
back in the head and then place the part of the stem protruding from the top
of the guide in an electric drill chuck and give it a decent spin while
pulling on the drill as hard as he could :)

The best thing to use on any gasket, including head gaskets, is what the
engine and/or gasket manufacturer recommends.

Most head gaskets these days are of a composite material that come
pre-coated with an adhesive which requires nothing other than the mating
surfaces to be in a suitable condition for a new gasket to be used (clean
and free from damage or blemishes in other words) and the parts assembled
and tightened in the correct manner (which the gasket manufacturer usually
advises). For gaskets that don't come with an adhesive bonding agent, which
these days would be limited to old stock items or plain copper sheet, there
are specific head gasket sealants such as Hylomar or VHT's Copper Coat which
are aerosol based that work particularly well with a *light* even coat that
will promote an effective seal.

The most important part of any head gasket seal, apart from the gasket
itself, is the finish of the mating surfaces on the block and head. If
they're not clean and smooth, then the best gaskets and glue that money can
buy isn't going to do diddly squat.
