NRHS is great to do business with. 
Here is what I posted in another thread. I did a stage 2 to my 883 heads and that left me the money for cams and ignition. This may pertain to you but you didn't give us any specs for your bike.
Heres a dyno sheet off of NRHS Web site for 883 heads.
This provides an idea of what to expect from the NRHS/Axtell Street Dominator conversion kit when used with your 883 heads and supporting components*. Only the head preparation level was changed between the top three pulls, all other components remained the same. The original stock 883 result is also shown for reference, in purple. That's right, with the bolt-on 1250 kit and these supporting parts, you can more than DOUBLE the power of your stock 883. You won't believe how much more fun your bike will be!

Yes I did the build in march I think. I did 1250 Jugs, 10.5.1 Compression Pistons, Stage 2 883 Heads, Shorter push rods, Screaming Eagle .497 Cams, Screaming Eagle Programmable Race Ignition, Ness Big Sucker II and a complete Cometec Gasket kit. The Cams, jugs, Gasket kit, shorter push rods and head work I got from NRHS. I have about $2800 in it. I did all the work and the install was smooth as silk. I modded my carb and intake myself, plus a couple things that I wont say but will tell you that they didn't cost a dime. I'm pleased to say it runs like a raped ape now. No leaks, no coughing or backfires ever, accelerates real hard. Once I change out my pipes this spring I'll be in the century mark with torque in the upper 90's instead of the lower 90's.
I don't have $6500 in the bike total including the price of the bike....I think it was worth every dam dime.

Yes, I did that conversion about 6 weeks ago. Highly recommend. If you have any questions, just call them, they are GREAT to work with. It was an easy install, and I have no problems with the engine. You might hear some negative about this with oil use. They did have a problem with their ring set on this kit for a while on the 04 and up engines. But have corrected that in the last year or so. I've had ZERO oil use.

Talk to Dan. You'll probably get transferred to him anyway, but he's the guy to talk to if you have questions.
