It works by creating a vacuum in the coolant system which sucks out all the air and pulls coolant in.

Here she is! Tickless!
Even though I am a Tech, I did not use air tools. All work done with hand tools except my airlift for coolant which is nice but not necessary. I still need to set timing. She stumbles a bit even though I cleaned out the evap ports. She did this before the cam and tappet failed. I do have a code 48 but I am not worried about that.
I really hope this thread helps someone out!

Great thread. You included many helpful details.
I have been running this same cam since 2009 in my GEMS 4.0. I noticed a difference in power for sure. I think fuel mileage increased in some situations as well. It hard to tell though because I installed the cam at the same time as a valve job, and all new gaskets.
As far as oil goes I researched the topic extensively. I feel that there are many quality oils that will protect the flat tappet cam without additives.
I have used Amsoil 10-40 and 20-50 Mobil 1 15-50 and Shell Rotella. It all depends on whether you want Dino or Syn and what grade you prefer.

Rotella definitely seems to be the standard for these motors. I myself wouldn't use anything else.
I am running Rotella 10-30 right now with no complaints. Rotella has been proven in many flat tappet engines.
I may try Mobil Delvac 1300 next time though, it is on sale right now at Advance Auto for $12.99 with an additional $5 mail in rebate from Mobil. You can't beat HDEO for $8 a gallon. Its a very comparable product to Rotella some say better, and I have had good luck when I ran it in my Powerstroke.

You really cannot beat that!
