Yeah, but how will this effect top end? Doing a slog up from Asheville, NC to northeast NJ, I spent most of my time at 80+. I don't want to make the engine busier for that same speed. I don't really care about hole shots, I'm more interested in having a strong pull at any speed. I also want high rev pull. My bike seems to lose oomph after 4,500rpm or so. I want pull up through 5,500rpm or so.

I guess that would depend on the cam (and the tune). On mine the initial start of throttle seems a little jerkier (maybe tune related and I haven't really ridden it much yet). In all other areas it seems smoother overall with just more "pull" feeling. Not to mention that it keeps pulling throughout the opening of the throttle where with the stock cam it seemed like it would level out in terms of how it "felt like it was pulling" once revs got into the 3900+ (not that I spend much time there). Kind of hard to explain from me at any rate, but it just feels like it has more to give whenever I want it. I certainly don't need to gear down for acceleration as much as I did before.
+1 ^ , at 13500 i did lifters with the mr103 and adj. pushrods,(not the quickies) per my tuner. No headwork or compression bump. Although like the 57 the mr103 can be set up to a max comp.ratio of 10.5 to 1( per s & s ), and benefit from headwork like most all cams would. Whatever you choose have a well qualified tune done. By the way the valvetrain is quiet , except for the click made by the ez start cams during shutdown. As you can see there are a handful of bolt in cams that will suit you just fine. Pick your poison and enjoy.

57h is perfect for stock compression. Gary at Andrews asked no more than 10:1. Some runnning 10.25:1 and any more is too much. The 48 tends to do better with tad more compression than the 57 iirc . There is a lot of choices out there. Riding style, desired rpm range and other mods and or future mods should make the decision more useful. If you plan headwork and or bigbore then wait and ask your builder whats best. If no plans for anything but cams then call and talk to few mfr's and explain your riding style and what you want out of the cam and you will find what you need.

Hi,
At 5,000miles you could bolt those cams in and probaly re-use just about everything if in good condition when you dismantle (the motor nothing special, just an internal combustion engine)
There a chart in SE catalogue which provides guidance on pushrod for SE cams and pretty sure stock are fine with se204
If you take tank off you are in for a pretty cheap mod on your dyna with probably all up at about $300
Thanks
