I'm planning a simple 95" build on a EFI 04 Road King. I'm boring my jugs, using SE flat top pistons, adding a TW26A cam, adjustable push rods, DFO tuner, high flow air cleaner, vance & hines headers with SE Pro slipons. I've got some money in the buget for some head work. WHat is it that I can do with the heads for low end torque?

Thanks for your help, I'm new here and appriecate all the advice I can get.

Welcome to the club. Check with our sponsor bigboyzcycles on the head work. The can set up the compression as desired for your cam. Believe it's about $340 for the heads including decking.
High end for a street bike is for example Dewey's stuff at www.deweyspegs.com. He likes the TW37G in combination with his heads.

PS: you may not need adjustable pushrods when you take the heads off anyway.

Head work helps on the top end.

If you had bigboyz do their thing (I think its around $300 but ask springer- to be sure) you could go with a TW37. This is a very reliable combo that ought to yield 100 HP and 100 ft lbs of TQ.

You'll be all :D :D :D :D

You mean that there isn't any low rpm torque to be added by doing work on the heads? I don't want 100 hp & 100 ft lbs TQ at 4-5000 RPM's I want it early.

Head work will help out over the entire RPM range. The cam you select will help determine at what range your bike performs at. Add a good exhaust and you are on your way to plenty of low end torque.

You may also want to think about gear drive cams, They are well worth the extra money....Its give you piece of mind...Don't know if it will blow the budget though.......Like V-hog said may be able to scrap the adjustables and save some money there....you must ask your head porter though......I see you are in P.A. you may want to switch the DFO for a powercommander as there is a reputable dyno tuner out there.(cant remember name though.sorry)

Not too take anything away from Springer...You might want to conisder the headwork of AMS for a mild build for baggers. Just a thought...

The builders listed below have all been used by either someone here, or someone on another board. Each builder has a different philosophy and method to their builds. Some will build it for maximum horsepower, others for torque. Most offer both a radical and mild build. Radical builds chase dyno numbers that can eat up a track at Wide Open Throttle. Mild builds tend to be more dependable and can eat up the freeway miles at cruising and riding speeds. Everyone will suggest a "package", or a combination of heads and cams that the builder has had success with. And here is the interesting thing, all the packages are a bit different. Each builder has a different way of working the heads, and thus a different cam is suggested. Each one may suggest a different exhaust too. Try not to mix up builders packages by trying to select heads from one builder, and cams and gears from another, and try to build it together. That may lead to problems.

For me, the thing I had to remember was not to get caught up in the HP/TQ numbers game (very difficult for me to do). All I really needed to do was let the engine breathe better, and run cooler, so it could work easier. My build with AMS heads in no way produces high dyno numbers when compared to others. But it does exactly what I want it to do.

And now, the list of builders I found posted on another forum:
