bike is 06 deuce having stage 2BB done next week would like to do gear drives but dealer says warranty is VOID if i do that heads are staying stock for now was also told upgraded se heads void warranty. 203 or 204 cam which is best choice thanks
been told by more than one dealer about heads lets see how much HO HO HO they have on dec 26th when im in person and not on the phone ill work em then thanks
203 cams will work good if you don't plan on doing anything to the heads. You're going to be disappointed with the Andrews 37 cams if you don't up the compression.
If you do non SE cams and high compression heads, you're going to have a hard time convincing H-D that they didn't contribute to a motor failure if you have one. H-D makes a 60 horsepower motor and guarantees it for 2 years. If you modify it so it makes 100 horsepower, you can't expect them to honor the warranty.
Last year I was talking with the chief engine builder for Woody's Blowers. Since then I have talked with a few other local engine builders. According to all of them, the stock '06heads are very good. For a low rpm/high torque build, they don't need anything at all. For a high rpm/high HP build, they just need a little clean up here and there. Unless you're building an all out effort motor, a full porting job isn't necessary. If that's the case, you'de probably want aftermarket heads anyway.

Even Dewey said that the basic 2006 heads are not worth sending in because they flow very well from the factory.
My dealer did an in-house clean up to my heads, and my bike runs VERY well.
