Weird, all these O/B SEUC²'s and one sarcastic red RK.  ;D

Didn't notice that till now.

I still contend that even though I would like the IDS (stock), the 50mm throttle body (stock), the upgraded frame, the 6 gallon tank, the ABS, and the key fob bag locking that I'm glad I have my FLHTCUSE2 in Black and Orange with the leather tour-pak.

At first I hated the leather tour-pak but now that I have gotten used to it and that it sets my bike apart immediately I love it.  Plus I hate the stupid latches on the side of the fiberglass pak.



Hmm looking at that logo I see black as the primary color with orange as the secondary color...... interesting  :drink:

I'm sure the heads are the same , just NEW guides. The 110" heads are CAST  and AFTER the valve seats are pressed in ,they BORE the seat and let the bore cut run down into the port around 3/8 " so there is no 'lip' from port to seat. The heads are NOT CNC  ported ! The heads in my opion are good ,as the ports are good {shape} but ,too big !  They use a 93% valve to seat ratio  !!!!!!   WOW !  Stock H-D is   89 - 90 % and  'most'  head porters use 89-91 % . When you use 93% ,you have NO seat to cut your angles on. Stock 110" has a very little 45 degree { .030 - .050 wide } and hardly no 60 degree { .010 - .020 wide } and if you install a 'smaller' seat ,you will have a lip ,because the port is already big. Only way to do it right ,is to weld the port and make it smaller. BUT , these heads do make pretty good power. I just 'shorten' the valve stem .010 then you can cut the 45 degree wider and get a 70 and 60 degree 'lead in cut' . I pulled 100 hp. and 114 tq. with stock heads and a Andrews 32 cams, stock T-B {46mm}  dyno 250 I , 5th gear run  SAE.  Pulled 100 tq. at 2200 rpm. Only use a TFI for tune ,stock rev limit {5500 rpm} bike runs great. I can fax you the dyno. DEWEY

It is true that all the heads are suppose to come from the same mold and the same cnc cutting is done. But with casting process, some times the holes are not alwyas in the same exact location creating a issue when you machine, tooling wear,.. you will see small changes in Chamber volume. We do our fair share or porting on CVO 110 heads and they are not often very close in cc volume ratio from front to rear. Typical varation is 1-2 cc from one to the next on a given set. But that being said the small changes should not drasticly alter the tune, as you already had a offset to start with.
