Default Twin cam

Would putting 2006 cylinder heads on a 2002 fxd be beneficial for gas mileage as well as performance

Minimally better performance. You're not going to feel it unless you have headwork done.

Gas mileage, nope

Best thing is do an off the shelf swap with someone like http://www.baisley.com/ and add a set of gear drive S&S 510 cams.
More power better mileage and in an '02 (last year Timken main bearing forged crank) damn near bulletproof.

If you have a set with the Single Bee-Hive springs they do flow a little better but the real upgrade is being able to go to a bigger lift cam..

Road Warrior I already have S&S 510 G cam with Gear Drive/ Vance & Hines Pro pipe/ 42 mm Mikuni carburetor. I wanted to go with flo headworks dual plugged heads but I believe he is out of business. I agree the crankshaft is Bulletproof .I'm looking to put in new Pistons rings and light head
work. My gold is reliability longevity and streetable. Right now I get 32 to 37 miles per gallon around town 41 to 43 on the highway. It's impossible to increase performance and gas mileage with the proper top end.The bike has 37,000 miles on it runs great just looking for more power
