About done riding for season. Time for cams and atleast head gasket. How much can be done to the heads and is it worth sending them off, thought I read that the 110 heads flowed good as is  . Figured if they make a big difference I just as well do it while it is apart!
Thanks in advance Scott

Plenty to gain, with the cylinder heads re-worked, along with a cam change.

Hey Shelby. Looks like we are barking up the same tree. Please throw in your 2 cents Scott. I have a 2013 CVO and am getting ready to upgrade. I have a local builder here in Missouri that comes with pretty good references. I went to him talking about doing the cam and Gasket up grade that you see on Fullsac's Websight, Andrews 54 with a Comitec.030 gasget. I tld him that I was looking for power across the total riding range. I also told him that this was a one shot deal, that I wasn't coming back for more power later (yea right, I know). I told him I wanted him to tell me what I ought to do to do it right the first time, I told him money wasn't an issue. I wanted sometghing ridable and reliable. This is what he came up with:
S&S 570 cam
Port and polish the heads.
I think hes doing some other head work like springs and valves also but Its over my head and I cant remember
Use a Comitec .030 gasket
Mill the heads in combination with the gasget to get the compression up to 9.8.
He stated he didn't want to do high compression pistons because its possible to have trouble with pinging and if you go out west (which I do) its sometimes hard to get higher octain gas
I noticed the Cams call for a compression of 9.1 to 10.0 on the S&S web site.

Does this sound all reasonable Scott ?

I know you're not asking me and I'm certainly no expert, but my 2 cents is that what your builder is proposing sounds very nice.

I would add that you should put in the S&S lifters as preventative maintenance, and of course the cam bearings. Like you said, you don't want to go back into it later.

If its a 2013 id ride it for a year at least and try to put 10000 miles on it before any major work. Maybe loose the cat,get some pipes fulsack etc and a tune. The hd guys will use any mods that you do to void any warranty work. If she runs good for that long then go for it. Doing to much though you will sacrifice depedablity. Ok for a hot rod bar hopper but a cross country touring bike it wont be

with my mods done to my bike i would trust it more then a stock bike ... jmo

Perfect I have a 2012 Ultra classic for touring.
I never could understand the concept of waiting for a year ? If I have a bike that I'm not satisfied with I'm going to ride it for a year If I ride it for a year then build it up and it breaks in 3 months does that make me feel better It's funny, I have never had a car or a bike that had serious problems while under warrenty.  They have always got me after the warrenty runs out.  Car and bike companies are like Casino's. They know the odds. They don't offer warrenties if they really think you are going to have to use it

There are a plethora of good cams available these days, and we use a lot of Wood, and S&S cams here, as well as certain Andrews grinds.

The S&S .570 is a good suggestion, and no more than 10.0 cr is correct.
