Has anyone attempted to remove those? They reach the cooling gallery around the valve guides.9/16" and impact air gun did not turn them.It is a '67 289.

:pimp: Try taking a propane torch or oxy/acetylene torch and heat the plugs up and then hit them with a candle to melt the paraffin into the threads, then twist it out with the wrench. Old school, but it used to work real good. :thumbup:

Why remove them, they are just there to plug up the core casting holes.

Well,I sent the heads to a machine shop to have the guides and seats redone.
They did only one head and said the casting was so rusty it will leak water around the new guides.I brought it home for inspection and decided to remove the Allen plugs for a good look inside.NG.It must be a NPT thread and well glued too.Ford must have taken the precautions to avoid water mixing with oil.I will try the torch and candle approach.
