The compression breaks the seal. My head gasket experience is limited
to an Alfa 1600 Giulia that I had years ago that blew head gaskets for
a while until I figured out what was what. It had sleeves also and an
aluminum head, chain-driven dual overhead cams and thereby two
proscriptions: don't use piston movement to move the head, and don't
take yer ball peen hammer and whack the soft aluminum head until it
came loose. I made a gizmo out of a piece of 1x3 oak, drilled holes
for the manifold studs, slipped the board on and whacked the board,
(gently) and the head always came loose with no problem.

I understand this, but what still confuses me is the need to turn the
engine over to remove the head, regardless of the presence or absence of
liners. The pistons don't contact the head (they sure better not!) in
their stroke, so what is being accomplished by doing this? Is the
compression just being used to break a seal?
