PLEASE don't do it this way. Remove them the old-fashioned way. Cut that tube
off with a saw and I guarantee you chips in the oil pan. Not good.

You pull the
-pushrods, remove the old tubes by cutting them in half with a Dremel /
-cut-off wheel or whatever and the new ones go in with a spring ala a
-Continental O-470 style pushrod tube.
