changes to my Heritage
This really woke the bike up and throttle response is greatly improved along with the sound, which was my main concern. Now the bike sounds like a Harley should sound. The indy wanted to use a PV tuner and with my very limited knowledge of electronics, I agreed. I trust his judgement, he has a great reputation and I have known him for years. So far so good. As I said, excellent throttle response, no decel popping to speak of, or any other issues.
To say that I'm satisfied with these changes/results would be an understatement ! The sound is just enough at slower throttle settings to allow me to keep the neighbors happy and very pleasing once you roll the grip!
Seems that some people are never satisfied because all my riding buds are now saying "what cams are you gonna use"??? Jeeze, I haven't even thought about cams until they started the questions. I mentioned it to a forum friend, but his situation with his motor was different from what I am doing.
Again, I am happy with the power this bike has. Actually sound was the issue, not a lack of getti-up and go. So, I have no plans to do anything else performance wise to this bike. I am willing to make changes that will add to the life of the engine, if this helped performance I would not complain.
But, out of curiosity I'm interested to know if there is reasons other than increased performance, for changing cams ?
Also, I'm wondering if the installation of an oil cooler is something some people do and if it is something that would benefit, long term? I'd like to hear some thoughts on this, pro or con.
Thanks in advance for your reply's. I find this forum friendly and very informative to a fairly new Harley owner who needs advice.

You got enough - enjoy!
Air cooled motors are designed to run hot and I've not read any studies that state that a typical hot running V-Twin hurts anything. That's not to say that a crotch cooler doesn't increase ride comfort.
If somebody knows something different let us know.

The 13's run hot. Yes, HD says they're designed to run hot, but heat will make it wear out faster...and the Softails do run hotter than ideal, even with a good Stage 1. Check your oil temp or head temp after a hard run in hot weather...you might be surprised to see them up near 270-300*.
The stock cams have no overlap, specifically to make it run hotter to help meet EPA standards. Mild aftermarket cams with some overlap will help cool it down some, will give you more power, and will also put additional strain on other components.
There are other ways to cool it down, the following is what I've done with my Heritage-
1. Tank Lift (good for 10-15* drop)
2. Coil Relocation (good for 15-20* drop in rear cylinder)
3. Wards Parts Werks FCS fans (good for 30+* drop)
4. Reusable, cleanable oil filter (5* drop and better power from less load on oil pump)
5. Jagg oil cooler (with thermostat so oil does not run "too cool") (good for 20+* drop)
And in anticipation of some saying, "have you have heard of a Twin Cam having a problem from running too hot in stock or Stage I condition"... Yes, have seen more than a few that required new top ends due to excessive heat messing up cylinders, valves and heads.

The Best of Harley-Davidson for Lifelong Riders
How much better? Lets say a 10th of a second. Is that worth it? In racing that can mean the difference between being a National champion and "who was that other guy"!!! Are we racing our bikes? No, but they are perfect examples of what heat does and doesn't do for us and the effects of heat on an internal combustion engine.
I put SE255 cams in and let me tell you it really woke up the engine. Twist and go. One of the best investments as far as I am concerned. Now I have the low and mid range power I need. And you can get them at a low price off Ebay.
