I haven't done any research on the HD SE 585 cams but IMO I wouldn't spend the money on any HD cam.
HD has to comply with the EPA requirements and that has an effect on the performance of the HD SE cams.
If you are looking at a cam mod it is best to go aftermarket.

I don't disagree that going after market would be a better choice but I don't think that all HD cams meet EPA standards at all. If that were the case they wouldn't have put the 259E cams in the 120 to make it compliant. They could have just stuck with the 120R with the 266 cams and been done with it.

This^^^^. If you look at the list of SE Cams most will state "For Race Application Only". Only a few of the SE cams are EPA compliant. Not sure about the new 585 cams though.

A lot of HD "For Race Application Only" parts are used in street bikes and HD put this label on most of their performance parts just to screw the customer out of the warranty. My 2008 came with a 96" engine but the 103 stage 2 kit with SE 255 cams I put in the bike was labeled "For Race Application Only" even though this same engine was available in the 2011 models except for the SE255 cam. That means that the SE 255 cam is a "race only" cam according to HD.
HD and the EPA knows that most of HD the bikes are going to have performance upgrades done by their owners and that is why the HD cam grinds are as EPA compliant as possible.
The way HD complies with the EPA regulations on most of their cams is in the intake/exhaust overlap, HD cams have less overlap than the aftermarket cams do and that is one of the reasons the aftermarket cams are a better option then the HD cams.

It does have a lot of torque, and it pulls really good all the way through the rpm range. I like it.

I had them put in my 15 RGS along with the SE heavy springs. Aside from the nice sound they make ;-) The torque and responsiveness is amazing. I rode it for a few hundred miles before swapping them out and at 3,000 RPM with a twist of the throttle, it'll throw you back in the seat. In 6th gear I can easily crank it get 10 mph gain in a couple of seconds. No need to down shift when passing someone. It's worth the $150 price tag and 2 hours of labor IMO. I put in the springs just because I was having the rocker box covers replaced with blacked out ones. It made it easier to put in the adjustable lift rods (which you need with the 585).

I'm wondering what the SE585 cam would do in the 120ST...? >:)

120ST 20% off thru my stealer... with a TB. Tune, Dragula 2's, and heavy breather intake, makes all the power I need.

I had a stage IV race kit installed with the SE 585 cams 2 weeks ago and it runs strong. Since I never did anything like this before I can't compare it to much. Another week or 2 and I'll get the oil changed and they'll put it on the dyno. It runs like a scaled assed ape compared to before and it sounds a whole lot better. I had previously had the dealer add the V&H power duals, Magnflow slip ons, AC, and super tuner.

The 259e is only compliant with a HD header and exhaust with cats. I don't think so much with a SE Heavy Breather Elite and D&D Boss Boarzilla getting 128hp and 141tq. I am really happy with this cam under warranty but will certainly entertain a Woods cam after.

The 266 eats the already shitty SE lifters. Buddy's motor is junk after 5000 miles.

Yes, I get that... but it is one of the ingredients.

I got 125hp/131tq with mine and I thought maybe a happy dyno but it runs super strong 3500rpm & up. Not real satisfied 2500-3500 though. That is a very impressive tq number for that cam.

Woods has great cams but I have a builder telling me to look at T-Man for when I'm ready to upgrade.

That is just a case of getting a crappy batch of the lifters. I know 2 guys with 120R's here locally and ride as hard as anybody you can put them up against and the stock lifters are still fine with 10k on one one and over 30k on the other. Also I rode with someone the other day on a 15' RGS with the 120RX and he has 8k miles on his with the SE lifters. Not suggesting at all that the SE lifters don't have issues but I wouldn't say that it is just because of the 266 cams. ( I could be misreading what you are saying ) They've been having issues in the 110's for a while with 255 cams. I did hear that MOCO has changed production on the SE lifters so I guess time will tell if they are better or not.
