No, the freeze plugs were in great shape so we didn't touch them. We did find one interesting thing, though. When the manifold assembly was removed, we found an aluminum tag siliconed to the side of the block that was installed by the engine remanufacturer in 1988. The tag read: 137101 TAM ENG. CORP TACOMA WASH 98411. I removed and saved the tag prior to painting the block.
