Square Drain Plugs in Block - How do you remove them?

rockyMember

I am working on my old motor, and I want to install petcocks, and possibly an oil pressure sensor in the front gallery plug.

After 43 years, all three of the plugs seem welded in.

Any tips to get them out, short of drills, chisels and taps?

They have had three days of ATF/Acetone treatment....

Thanks -

Rocky
