Hood clearance?

Hey guys, Happened to think of it while tinkering in the garage, I read where some of you have hood clearane issues and go to the early buulnose style valve cover to gain a little extra, well maybe even one better, how about the early early valve cover from the 75-76 20R engine, it used an Oring in the cover type screw-in cap as opposed to the Oring in the cap with the threaded tower. Just a thought.
