The way I removed them is with a punch ..
Hammer on one side to get them tilted in the bore then with vice grips pull them out of the block ..
A few of them was so rusted that the punch broke though the wall ..

Most certainly they was going to leak in a very short time if they wasn't replaced ..
Always do a replacement when rebuilding a motor .. Save a bunch of grief down the road ..
And easy insurance for a very long time especially with the replacements being brass.

Agree on changing freeze plugs, because it’ll never be the one that’s easy to get to that starts leaking.

Always be on the back of the block or behind the motor mounts.

6 qts in the pan put the cold full level mark in the middle of the zone ..
Did just a small amount of trimming to dial in the full level ..

Got super lucky without the need to get into a huge job ..

Next to do is to add some support brackets ..
... Dipstick is done ...
