screaming eagle 211 cams question
That cam likes high compression. Unless you change your pistons to bump your compression ratio, you'll probably be disappointed.
And, if you're exploring headwork to bump up the CR, there are better cam choices from the aftermarket.
Judging by your username, if you have an 06 stock 88" motor, you'd probably be better off with an Andrews 21, or possibly an Andrews 26 if you're thinking of going big bore.

I didn't know that about the SE211 cams! See what I mean to those who treat new people poorly or an experienced rider who asks a simple question that most thinks an experienced rider should know or ask a question that has been covered many time but a question that is new to them?? I now know why the SE 211 cam was recommended and that was picked to be used on my motor. My build is a high compression motor. I still learn something new almost each and every day. This site is GREAT for many reasons but the knowledge used and shared here is tremendous.

Hmmm...the best advice that can be given about cams is to really be honest with yourself about your riding styles and needs.
For that I mean, do you ride 1 up, 2 up, combination, etc. Where do you want your power? Low RPM grunt, or are you looking for something that will hit it's power a little later, say around 2800 RPMs, but carry through to redline?
There are so many good choices out there, and most people only really experience the cam they choose, and have a limited depth to formulate facts.
Andrews grinds cams for a variety of other manufacturers. They're well known, and they're some of the less expensive options out there.
If you're planning to stick with a stock 103" engine, you might consider either the Andrews 48, 54, or 57. I'm personally in the middle of an upgrade to the 57 in my 110".
If you're concerned about staying with SE parts, the SE255 is a good cam, with lots of low end grunt. It's stock in the CVO bikes. The torque down low is strong, but the cam runs out of breath around 38-4200 RPMs. CVO 110" motors have low compression. But...the SE255 does run hot.
You should feel comfortable calling various manufacturers like Andrews, Woods, etc, and even call Fuel Moto, Hillside Cycles, etc to discuss how you ride, and what they'd recommend.
Bolt in cams are numerous, but nearly every cam will perform even better with headwork. That's where stuff started to get a little pricey!
Good luck!
