The head fins were changed in 2009, so I don't think the manual compression releases will work, but the autos are not that bad to install, if the dealer has the jig. For long term reliability, I would go with gear drive on the cams.....and S&S offers cams with a built in compression release. As far as 110 or 113, well, unless you are an extreme adrenaline junkie, why waste the $$? Splitting cases and boring spigots for the extra power just doesn't seem like a necessity, and neither does that kind of power on an everyday machine.....I have just over 100hp, ridden everyday weather permitting, and sees 100mph+ every day I ride it.....and it is more than enough to get me into trouble. I have to be really careful in the rain....if you DO have that need, make sure the combustion chamber is polished (Harleys are not, and carbon does build up) ......Jims is a way to go, so are S&S setups.
