First I want to say thanks to Black Bart, rod18cdz, and jamess71 for their comments earlier, sure helps me to stay on top of this thread.
No head gaskets yet...... Had to work on something so I opened up my S&S Quickee prs for cleaning. Have heard that some pr kits are quite dirty but I found the S&S kit very clean although I did find a couple of very small metal shavings - made it worth the effort.
A couple of other notes: There is a Supplement included with the pr instructions that states that on Big Twin engines there are two long and two short prs. I could see no differences at all so I called S&S tech and he confirmed to me that all the Big Twin Quickees are the same length now. The S&S kit does not include everything, you must reuse your Spring Caps, Springs, and Flat Washers from your stock prs. Those 3 items are shown on the right side of this pic:

Waiting on parts Blows! Especially when you are so close. In the long run it will it will be just a blip on the radar.
I had several setbacks during my build. The final one was, once I got it started there was an exhaust leak that was hard to track down. Turns out the bone head tech at HD that I had install the ACR did not tighten one properly and it was leaking.

The last thing I want to do is waste money tuning a bike that has a mechanical problem.Jamie from FM has already sent me a new map for my build. He acknowledged that he was not too familiar with my set-up but said it should be a good starting map. So I could use the starter map and my PV Pro AT to get the bike up and running and shake out any bugs before heading to the dyno.

How did you know that you had an exhaust leak? Was it the sound or something else. Ed from the Dyno Difference wants me to just do a few heat cycles and trailer the bike in for break-in and tune at the same time but I am worried that everything may not be perfect and if I break it in, I can chase down and resolve any issues before dyno tuning.

Next I double checked the push rod adjustment on the front cylinder ( the cylinder that had the noise ) and removed the rocker cover just to look. To no avail, Still had a ticking noise that I was convinced was exhaust.
Next step, disassemble until I found the problem. I pulled the front rocker Assembly without loosening the push rods then pulled the lower rocker box so I could get at the ACR. As soon as I put some pressure on it I could feel it rock, just barley but movement, not good.
The reason I had the ACR's installed by HD is that I did not have the socket. Figured How often would I need that in the future and I had already spent a few bucks on this project.
Needless to say, I now own the ACR socket. The engine is quiet as can be and I am as happy as can be.
I believe people make alot more out of break in than needs to be. I was a engine builder for years. Working on a national and sometime world wide level. I've seen and done break ins many ways.
A dyno break in is fine and so is doing it on the road. It's your motor and your money.

Thanks for the info, your knowledge and posts have been very helpful. 
Can't wait to finish up, but the slow down has given me extra time for cleaning all the fasteners and their threaded holes - amazing how much gunk there is to clean, mostly HD thread-locker, but nice to start clean again.

Alan,
have been watching this build with interest. I viewed in another thread where you had installed an exhaust system already. Ergo I am assuming your build is completed?
I am also guessing that you are waiting (on weather of course.. arent we all? 'cept you east and west coasties) to complete a couple of heat cycles and break in riding? before dynoing it and posting your results here?
I am using a set of 2 into 2 exhaust similar to those and as well know they dont have the scaveging abilities as the 2 into 1s' thus what type of HP and TQ dip/loss do you think you will experience as a result?
Sorry for all the questions.. living vicariously through this thread until I can get my own act together to do a similar build.

Got a letter from Cometic today with a UPS tracking # so I checked and the new head gaskets should show up tomorrow but I leave again the next day for a 4 day trip
If they come early enough I will install the heads.Today I filled up the primary with some Belray, then I installed the S&S lifters and the lifter covers. A 6" Ball end Allen wrench(3/16") made torquing easy - have heard about others just using feel on the inboard fasteners. One other small learning point, I was unable to use my rethreading tap on two of the lifter cover holes because of the cylinder fins - should have cleaned those holes when the cylinders were off.

hey Alan, got mine all sorted out and took it for a nice 100 + mile ride yesterday.
I realize that saying this right before you leave on four day trip when you are so close to being done is tough, but it was a blast to ride.
I ran it pretty much how I would ride normally just not as hard. hit 5000 rpm's early on and up to 6000 rpm,s at one point. The rev come on a lot faster than before. she ran great and never had a hick up.
Definitely need a dyno tune, just not as crisp as it should be.
As for torquing those lifter cover bolts, I switched to 12 points during this build.
