I am at my wets end the dealer has put the se254e cams in the se stage 1 ac Vance and Hines power duels with there twin slash rounds and the download for the cams and pipe/ac combo it is somewhat beater but not what it should be I am ready to pull the heads and get some work done . I need your opinion as to what would you do in my shoes . I had a frend give me a wood tw555 cam set trying to help me out but is this the way to go ??? I ride hard lite to lite looking for that pull hard toque when the wife is not with me .when she is and I try that I get hit in the helmet a lot 
if you know what I mean . tq in the 115 + and hp 100+ with the flattest toque curve possible 2000-5000+ rpm . am I off my rocker or can this be done ?? the cam that is in the bike spec lift I .535/e.536 duration @.053 i224/e234 timing i-01atdc/43abdce50bbdc/04atdc tdc lift .094/102 the woods cam is lift i-555/e-555 duration @.053 242/242 timing intake 20/41 ex-42/18 tdc lift in .189/ex178 please what can we do here I would like this to be the last time I do work to this bike

Well, I don't know. I'm perfectly happy with my 96" Road King. It has plenty of power for me and jumps up to speeds way beyond the speed limit in no time at all. Never have a problem pulling away from traffic.
Maybe a V-Max would satisfy your need for power more than a Harley will.

what to do
Hey guy,check with some of the site sponsers here I'm sure they can give you some direction. Fuel Moto is one but there are plenty here.There seems to be plenty of guy''s running those cams without ay complaints ,maybe a good tune will help. Good luck with getting the results you are looking for. Jim

You need to add some compression, get the heads flowing, and put a cam that will work with the combo. You already know that.
The 555 is a good cam and is the cam of choice for the Fuel Moto 107" kit. Pretty good results reported for that combo. Add heads to it and another 10/10 seems to show up.
I'm running a science project 103" with CP flat top pistons, Head quarters heads, TMan 590 cams, stock throttle body/injectors, and a Road Rage pipe. Getting 114/120 with a really good tune.
Your goals can be reached. Stick with a proven package from FM, Tman, Headquarters, etc. Best way to achieve your goal.

I do believe that you have a cam designed for a significantly higher RPM range than you are using. Sometimes too much of a good thing can be counter productive. Even the Woods 555's may be a bit too much for how you run your bike.

Just came off the fm site looking at the 107 kit they have and the dyno #s with the tw555 cam and stock heads looks real good the only thing is the cylinder strong enough to take that much power and heat ??? can you safely take that much out of a stock cylinder ??? the combo is close the jack pot head pipe and the v&h power duels are somewhat the same I think they use a heavy breather I could do the work in a day and then get it tuned . It could be that it just needs a good tune and I am get to far ahead of myself. Has anyone had good luck with the se 254e cam set??? Or do you think this could be most of the problem
