I heard that LT's would clear a manual transmission but not an automatic, if a tranny need to be pulled. I do agree that it is a long PITA process, I was doing a head swap at the same time and even with the heads off I had to unbolt the motor mounts and jack up the motor 3-4 inches to clear the LT on the passenger side. Then bolting them down once i had the heads on was a long process as well. I used the stage 8 locking header bolts and a gear wrench and for alot of the bolts I only had enough room to turn the wrench one click at a time and then did one heat cycle re tightened and put the locks on and have not had a leak yet beside from the egr port but that was pretty easy to fix. Overall I say go for it because from what i have seen shorties only yield a couple maybe 3 extra horsepower.
