I have an 07 FXDWG.
Ill will shortly be adding the following -

D&D FatCat 2 into1, possibly the Terry Components TVII or thunder-max w/autotune (either one of the two), Arlen ness Big sucker and Head Porting.
Looking for a bit extra HP/Torque as well as the super reliability of a close to stock motor
Who does the best porting job, has the best Value for money etc?

 

This will draw a lot of responses.... so let me be 1st!

I have Zippers heads on my scoot and i am very pleased with them. i have 110/110 and i get 34 mpg in town to boot. a lille dead below 1600 though. I have alos heard that the head shop and cycle rama make some mean cylinder heads also..

 

HQ...Hillside...GMR...T-Man...Zippers.....The head work is where the power is.....You can see from my Sig. who I used

 

Weuse R&R cnc ported heads because we believe these are the best. They take out the core shift on the fly, have great velocity, and make sure the numbers are balanced from front to rear which smooths out the engine vibration.

 

You can't beat Big Boyz for value for the money, under $400 gets you port/polished heads, cc'ed and milled for equal and bumped compression.

Give Bean a call and discuss your goals, he'll take care of you and not push crap on you that you don't need.

there are several good ones and all have different levels of head work but quality cost

Hillside
GMR
R&R
Big boyz
You can see my choice but these are all good

 

All of the awnsers are great as the most imprortant is a balanced build with componets that go together as Phil would say.

You can over cam or under cam a build, along with all the other componets that should go together. Whoever does the heads should reccomend the whole package.
