I got this book from AMC published in 1972... In the section Mode 3 (7,500 RPM Capability) they have this picture of an Oil drain-back lines for road racing..

I'll try and put a scan later but the basic idea is to install oil lines from the two oustide corners of the valve cover, close to the base and route them down to the oil pan... I figure it could have potential for fourwheeling when you're at angles most of the time and allow oil hanging around to drain...

Anybody did this before? Any thoughts?

Here's the scan:
