Best liquid cooled heads?
I have a 16 road Glide ultra with an H-D 110 drop in kit (factory heads, throttle body and injectors and 585 cam). Just had her dynoed and pulling 101 hp & 127 ft/lbs torque.
Considering upgrading the throttle body, injectors and heads and I'm curious what options might be available out there for ported heads. I know having the liquid-cooled heads substantially reduces available options and wanted to see what you guys might be running to improve performance.

I chose the Harley Screamin' Eagle CNC Heads. Part Number 16500208 when I went with the 110" Bolt-On Kit. I'm also running: an Andrews 57H Camshaft, 0.030" Cometic Head Gaskets, an S&S Air Filter (P/N 106-2091), Harley Street Cannon Slip-on Mufflers and using the TTS Mastertune software (which I've used in the past and like).
I'm quite pleased with the results. No Dyno Sheet, but even with an upgraded Clutch Spring (Harley P/N 37951-98) I do have to exercise good judgement or I'll be needing to purchase another clutch in fairly short order.
As for the heads . . . I chose the S.E. Heads for three reasons: 1.) I wanted to keep my original heads (just in case). 2.) Sending my original heads out for an independant shop to work their magic would have generated a down time that I didn't care to work with. 3.) Given reasons #1 and #2 the pricing of the Harley Heads was "relatively" attractive. I paid $815 for mine via one of the popular on-line Harley Dealers.
I did hand polish the combustion chambers. See attached before and after pictures. For fluid dynamics reasons I left the intake and exhaust tracts pretty much as the CNC machining process left them.

I should get my bike off the dyno later today.
I have a fuelmoto 110 kit, .045 cometic gasket, and Woods 999-6 cams. With the CC of the chambers, that gasket and the -1.5cc dished pistons, it put my static compression right about 11:1. My heads CC'd to 79.6 and 79.8 CC in the chambers. Just something to help anyone in the future.
I also went with fuelmoto port work, and I was happy seeing the port design and how they unshrouded the valve guide.
I think their price for the work is a good value. I've also handled a set of zippers twin cooled twin cam heads and was able to compare them directly. The heads took two completely different approaches. The zippers heads had more work done on the back side of the valve, in the throat. The floor, while opened up, was left relatively flat and broad. The fuelmoto heads had more attention applied to the guide, and the even shaped in a sort of blade edge leading to the guide; but they did not do as much work deep into the throat.
I was able to buy a spare set of twin cooled heads for very cheap and had them sent off. My down time was limited to 4 days.
