Guide liners are spring tempered phosphor bronze. They are hard, not soft and broaching them to size likely work hardens them a bit more.
If installed correctly, they work fine.

Which method I use (whole guide or liner) depends on the job and the type of head, I have no problems with either.

It seems that just because a manufacturer of valves uses the term "super alloy", folks seem to think a special "super alloy" valve guide is needed for them.
Thanks for clearing that up

Hi Keith, not my case... As there are some materials and bronze alloys you can made a guide of, I was just asking if the Ferrea "super alloy" would just prefer a particular one.
