Joe-
Boy, am I glad you mentioned this method first...
I have used exactly the same method (socket and all) with great luck so far.
I was gonna email this solution, but thought I was probably the only "hammer"
mechanic on the list and didn't want to get the award for being far too
"agricultural" in my approach. <g> My only additional comment is that if you
do this on the bottom of the head after it has been surfaced, run a small
file around the outer edge of the tube as it gets kind of "smeared" over when
the grinder goes over it and leaves a little "tail" on the outer edge
sometimes.
Remember... a little oil leak is OK. You wouldn't want that block to rust !
