The ignition timing on the HD download for the 117 kit is very conservative. Missing around 10+ degrees all over the map.
Without proper ignition timing one can not expect the full potential (Tq/hp)  from the engine.

This has a bigger effect on power than AFR.

Big radius pipes are probably killing your power. Having said that, that is a beautiful torque curve- hits high down low.

They did a full dyno tune and not the download tune from HD. The bike runs great but was just curious why there is such lower power.

I'd bet on exhaust

[CVO AV8R]

What exhaust would help out on power? 2-1?

Would a "B" twinkie vs "A" twinkie make a difference too?

They (2-1) usually do.

Mine has custom made CP pistons for 11.4 to 1 compression, Head work by HD street performance, 5.3 injectors, HPI 55 throttle body, woods lifts and cam TW-9B-6 cam.  Fullsac exhaust.  138 hp and 140 torque.  My dyno sheet is in this thread, a long flat torque curve.  Bike is a blast to ride.

I'm considering Woods 999-6 or the 9B-6 for my build. Wondering about lifter longevity with these cams.

With reasonable spring pressure not any different than your current cam.
You will need to be sure the springs will go to the new lift and also be aware of added TDC lifts.
Either of these cams will have a hole down low if not squeezed hard enough. The 999 will be more particular on the pipe choice.

I do have a 117-Kit installed and would like to know if a Head change helps to increase TQ & HP?

Would the SE PRO MAXIMUM VELOCITY AREA (MVA) CYLINDER HEADS – CNC PORTED (16925-11) or the SE PRO CNC PORTED FACTORY HEADS WITH VALVE UPGRADE (16500013A) a suitable solution to achieve more TQ & HP?

Or is there any other recommendations?

Thanks

I have had consistently better results with hand ported  OEM heads.

Thanks for the reply. Would I need to check lifter wear periodically as mileage progresses? Dealer claims every 7000 miles with these high lift cams.

i have 38k plus miles on my build w/625 lift and have never touched it

[Unbalanced]

10k-12k is where some of us check them.  I try to prevent what I can.

Don't know anything about this dealer so I could be wrong
I was trying to get a look at the runfile number but it is cut off
I think the dealer would start with the download tune and go from there
He may have just got the AFR sorted ,  . there is no AFR graph
and most dealers would not have a clue about timing
and as ultraswede has suggested , you could be missing out bigtime there
