77 stuck engine

[timberbeast]

I have a 77 with a stuck engine. Pulled the head off, soaking pistons. Turned the crank with a bar and the sleeves are moving inside the block. Once I get pistons loose, do I have to re-seal the sleeves? Pistons are moving a little, will let them soak a little more.

You should replace the o-rings on the sleeves that have moved...

I would be checking the rods also to make sure none are bent.
