Finally did my breather bypass (pics included)

No AN Refers to a fitting if you are going to use threaded connections on the hose versus Hose clamps
Hope that helps
DK has some real nice setups
here is a link
I like the drop down filter

If I am using a NPT to AN fitting to go into the head, can the adapter fitting replace the breather bolt? I would think that it would, but before screwing something up I wanted to make sure.

I just ordered the DK Customs Complete HiFlow 606 Air Cleaner Dyna Softail Touring - Rushmore because I like the stock cover. I am going to try the breather bolts - any thoughts on how much oil will weep out of the bolts?
My most recent two 103's are opposite sides of the spectrum, one I am running Outlaw Breather Bolts and about every 1000 miles there is a very light mist that takes 30 seconds to wipe down.
The other one will do that much mist in 20 miles of riding, so I use the Premium Discrete Breather System.
Here's a thread with more information about blow-by and how to reduce it.

No, the filter does not breathe from the front face. It is not necessary, the filter breathes more air than a Twin Cam can eat. Here's a LINK with more photo's, Dyno Chart and info.
Yeah, we've tested 8 different catch cans over the last 6 months. This has been the only one that I've really liked.

This is an External Breather System (EBS) that I've been testing out recently.
It is one of our Premium Discrete Systems where I've replaced the filter with a catch can that has a built in filter.
I'm liking it a lot. After testing I was going to go back to the Premium Discrete, but I've decided to leave this on there.

Oh I know that I used them in all of my race cars in the past. Maybe I should have been more specific:

But Ill bet the threads are not NPT in the head.
Maybe some one knows for sure
I can look at my old bolts tonight when I get home
Re: Straight Thread Vs. Tapered Thread
I'm not sure if this is the info you are looking for but
a straight thread is the thread you would find on a bolt and nut.
a tapered thread is the thread you would find on water/gas pipe connections.
a tapered thread is a sealing thread.
a straight thread is an axial load bearing thread.
a straight thread does NOT seal by itself but needs a gasket or needs to be part of a tapered surface to seal. an AN/SAE fitting has a straight thread and the sealing surfaces are mating cones.

I have a FM Pro-Billet a/c, and ran vacuum hose from the breather bolts to the bottom of the a/c, drilled a hole through the bottom of back plate, then used a T fitting to connect from there to a fuel hose running across the front of the engine into a catch can (from Wimmer Custom Cycle) attached to the left down tube, with optional petcockk for easy drainage. You can't see it in the photo, but it's vented on the other side of the catch can. Works well, and with fairing lowers the whole set up is hardly noticeable. And it doesn't interfere with an oil filter change. Unplug the hose, and use an allen wrench to loosen the clamp and slide it to the left. It's a little pricey, but it works for me.

As Kevin pointed out, all twin cams are different and your twin cam is probably one of those that never needed it to begin with so in your case, yep it's bling.
