Depends on how deep it is. Also, head gasket sealants are not usually
effective - although I;m sure there may be some that work - perhaps someone
has some 1st hand experience?
Most head gaskets have a copper sandwich that is supposed to take the shape
of any imperfections and prevent gas, under pressure, from escaping. It's
a very difficult environment for sealers to survive.
I suggest you ask your machinist to take a look and advise you - if it were
me and there were any question, I'd have the surface touched up - you;ll be
doing a lot of work to put the engine back together and building it on a
imperfection may cost you money & time. The machinist will also be able to
advise if there are any "Mechanics in a Bottle" which may work.
Good luck -

Subject: [MBZ] Head gasket sealant?
Received my machined block and head for my W123 300D and unfortunately
managed to scratch the surface of the block which interfaces to the head
in a few places during transportation. Should I just leave it or can/
should I apply a sealant to the affected areas?
Peter
