: The guides are a press fit into the head.
: To get them out you would need to
: press them "through"... which
: would mean dropping them (and the
: valves) into the cylinder bores. The
: new valve guides then have to be
: pressed into the head to the correct
: depth, their through hole size reamed
: if necessary, and finally the valve
: seats have to be re-cut to run
: concentric with the hole in the guide.

: So it really isn't possible to replace
: guides with the head on the block.

: As you mentioned, you can replace valve
: guide seals with the head on the
: engine... but what's involved is
: totally different and all on "one
: side" of the head.

: Has anyone replaced valve guides
: without
: removing the head? I remember
: replacing the oil seals on a Datsun
: 240Z without removing the head. I
: remember inserting a rope in the spark
: plug hole to keep the valve in place.
