Gently stretch them a little bit. They should stray stretched long enough to get the head in place. Carefully lower the head and give it a slight turn left and right. you should feel the o-rings seat properly. If you are really having a dificult time you may have the wrong size.

not uncommon based on others experiences (on this site) to be given one or both incorrect o-rings from the dealer. If they really don't seem to want to fit you may want to double check them. But as others have said, warm them a little and stretch them gently. They should easily stay put with a little grease.
Good Luck!
