The HS 1.7's increase lift only, they don't increase duration which is the measurement that makes a cam "bigger." Anytime you upgrade a cam, you will need to make changes to your tune (computer) so you can take advantage of the power gain.
When you are comparing duration numbers, they all need to be at .050" tappet lift. If the cam grinder can't supply that number, then I wouldn't trust the advertised duration.
