When ever I rebuild an engine...I remove all plugs to give access to oil galleries.
I am a bit paranoid...so I thread each place that the plugs were removed and then screw in hex type plugs.
If you use pipe type threaders...you will seal the galleries without sealant (goop or silicone).
This gives me great peace of mind knowing that the plugs will never "push" out under oil pressure.
