Is it ok to run heads vertically?

Sure.....they sound better vertical, man.
Really though, if it's fan cooled and no vents are blocked, it's fine...a non-issue.
Cooling problems could occur if it's convection cooled (heat sink, no fan), or a tube amp that ends up putting tube heat back into itself.

My SKB rack case actually has feet on the side of the rack for it to sit on, so I'm thinking its okay. I've run mine like that a few times and had no problems.
It has nothing to do with the feet on the side of your rack, but what is mounted inside the rack, and how that gear is ventilated. The side feet are great when it comes time for load in/out.

If fan ventilated OK. If convection cooled maybe not, as those are designed for heat to escape by rising, which can be upset if not placed in a normal fashion.
Depending on how the output transistors are oriented in the amp, if you turn the amp vertical the electrons will either decelerate due to gravity if the collector is now above the emitter (drain and source for FETs), or accelerate in the opposite case. This could lead to phase alignment issues.
<edit> Ooops. I forgot the requisite smilie.

Fan comes out of the back of my amp, I think I should be okay, but I do agree on the topic of those feet during load in and out.
In mid 1980's,the only time my 1974 Acoustic 370 head ever went in for service was due to my error; I caused a short in a home-made stereo cable for an experimental rik-o-sound cord and blew a fuse, which welded to the casing.
The repairman, Rodger made simple repairs for free, as Acoustic as well as KUSTOM had a lifetime warranty in those days. Rodger owned a 370 head as well and admonished me to never set my 370 head on top of the cabinet, as the vibrations produced are so intense, that they can shake things loose in a head. He used his head vertically, standing on the rubber feet.
The thought of my 370 head tipping over caused me great anxiety, so from then on, I have used a folding restaurant plate-server to isolate the head from the cab. Although a 370 deserves to be placed on a proper pedastal of some sort.
