Lost count of the blocks that had one or more of old expansion plugs left inside. The winning block had two sets not counting the ones I knocked in. Ended up with a big pile of old steel plugs. They just settled to the bottom and didn't hurt anything. Engine cooled just fine when it came in for a performance upgrade.
