Even though the liner notes said this was the 161 minute version, they LIED. It was the 179 minute (endless) version of the movie.
Are the added 18 minutes just a few scene additions, or are they tidbits scattered throughout?

I think several scenes (maybe three) were added back in. When I get to the deleted scenes, I'll see if any of them are now in the movie I watched this afternoon.
I have the extend cut on DVD
These are the extended scenes
1) After being betrayed by Blondie, surviving the desert on his way to civilization and assembling a hybrid revolver from parts of various original makes, Tuco meets with members of his gang in a distant cave, where he conspires with them to hunt and kill Blondie.
2) During his search for Bill Carson, Angel Eyes stumbles upon an embattled Confederate outpost after a massive artillery bombardment. Once there, after witnessing the wretched conditions of the survivors, he bribes a Confederate NCO for clues about Bill Carson.
3) The sequence with Tuco and Blondie crossing the desert has been extended: Tuco mentally tortures a severely dehydrated Blondie by eating and drinking in front of him.
4) Tuco, transporting a dehydrated Blondie, finds a Confederate camp whose occupants tell him that Brother Ramirez's monastery is nearby.
5) Angel Eyes appears at a Union camp, where his affiliation with the Union Army and his rank is explained.
6) Tuco and Blondie discuss their plans when departing in a wagon from Brother Ramirez's monastery.
7) A scene where Blondie and Angel Eyes are resting by a creek. A man appears and Blondie shoots him. Angel Eyes asks the rest of his men to come out (all are hidden as well). When the five men come out, Blondie counts them (including Angel Eyes), and concludes that six is the perfect number. Angel Eyes asks him why, mentioning that he'd heard that three was the perfect number. Blondie responds that six is the perfect number, because he has six bullets.
8 ) The sequence with Tuco, Blondie and the Union Captain has been extended: the Captain asks the pair questions about their pasts, which they are reluctant to answer.
There was also a long more brutal scene of Tuco being beaten up, but the quality of the negative was poor.
Eastwood and Wallach went back into the studio and dubbed their dialogue into English, Since the scenes were never in the original US version, they didn't dubbed the those scenes.
