Technically a 1.8 roller would give you more valve at low cam lift areas than stock would, but I am not sure if it would do anything to change the power curve as LSA and duration is not going to change.

Stock is better than a roller tip. The way the tip is designed will give you more lift than a roller tip. ZZP has an article on it somewhere.

stock rockers are equivalent in lift performance to a 1.8 rocker. Its never been proven that 1.8s make more power either.
