I found a heavier punch with a bigger end on it. They came out in a couple minutes. They drove into the block but I grabbed one side with pliers and got them out. Thanks!Break them loose with a hammer and punch first. Hit one side
Also, it looks like there's a few small freeze plugs on the head where the exhaust manifold went if I'm thinking correctly. Take those out also? And what about the ones on the back side of the block also.
