Tim, call Eric Hinderberger at Performance Engineering - 513-738-5001,
pecobra@aol.com,
http://www.perfeng.cc/#. He built my engine and is an absolutely amazing source of information. My SPF is a street style roadster, but it does have a hood scoop because I went with a Air Gap manifold. Lots of other street style guys with a variety of engines and no scoop lurking on this site and Club Cobra.
Good Luck!
Terry
