Sustained high speed running problems?

I remember years ago someone with an 03 Cobra mentioned that they can have oiling issues if run at high speed (over 130 mph or so) for too long. I've also read a bit about oil pooling in the heads and drain back kits to help with that. Any issues like that with the 05-09? I usually drive my car pretty mellow but if I decide to open it up, anything I need to be aware of?

Thanks in advance

I'm pretty sure any such issues would be related to engine speed (RPM), not vehicle speed. And there are lots of 05-09 Mustangs that are run on road courses at sustained high RPM with no common issues that I know of. But even on a road track it is very unusual to have sustained speeds over 130 MPH.
