Glad to share info... there are actually 4 critical vertical measurements that you have to watch for:
1. Floor to ceiling height. 107" in my case
2. Floor to bottom of lift rail (ramp if you like) and in my case in the 4 post locked position which allows the C6 or ZR-1 to be on the bottom is 50" and the height of the C6 (which lowered 7/8") is 48.5" and the ZR-1 is 47.5". Point is with a low type ceiling (which I consider mine to be) you have to watch the height of the cars. Some say it looks tight...well it is but whether an 1.5" clearance or 1 foot clearance- clearance is clearance.
3. Floor to garage door at its closest point to the floor height which in my case is 95". Just to feel comfortable with that height when I use top spot to park the ZR-1 it goes nose forward and the C6 opposite (see above pic)..this pic show the nose forward combo>>
4. 4 post column height... in the case of the Direct Lift Pro 8S I have the columns are 84" which easily clears the garage door when open.
Basically if you have two cars that are 49"-50" in height each and have a ceiling that is no lower than 107" and use a Direct Lift Pro8 (lower column height and the deck lock points are at a good height) and a garage door when open that no point is closer to the floor that around 94" then you are good to go. More ceiling or garage door height then most assuredly good to go.
If you look at the center drive garage opener and the metal garage door rail ceiling brackets you can see how much door open height is gained with the Lift Master/high lift garage door rail set up>>

I'm still getting over the sticker shock of the ballpark quote I got for raising the rails, changing the door springs, and installing the 3800, so I don't know if I'll end up going that route now or not (in the middle of dealing with a hail damaged roof, too...gotta love timing, huh?!
), but all of the info in this thread is much appreciated!

If you have a 10' ceiling, you can fit any combination of C3, 4, 5, 6 on top or bottom with the regular center garage door opener. I still have 6" clearance between the roof of the top car and the opener and plenty of space for the bottom car.
Sweet!

I am changing the door opener to the jackmaster 3800 and plan on running the garage doors straight up the 14 foot wall to make room for a 4 post lift. To change the 2 door opener and springs is going to run me roughly 2200. I received quotes as high as $3000. If you are in NJ I can forward the company I am using.

Thanks for the offer AC, but after getting an on-site quote that wasn't quite as bad, looks like I may be back on track to getting the Liftmaster 3800 afterall. 
For those that have the 3800, is it compatible with the built-in Lear remote in the Vette sunvisor? My existing opener would never work with the Lear.

The Liftmaster 3800 jackshaft opener is the way to go with torsion springs. Absolutely nothing overhead. I'll soon be installing two of these in my outbuilding. My main garage has three 12-year old Liftmaster belt drive openers in it which have been completely trouble free (the 3800 was not available when the house was built). When they fail (and if I can't repair them), 3800s will go in.
Liftmaster/Chamberlain/Craftsman are built by the same folks. The 3800 is only available as a Liftmaster.

I just put 2 3800s in this year, they lift my 10ftx10ft doors no problem, and they are pretty heavy, r18 insulated.They work fine with both my vettes home link and Lear.
