Painted Stealth heads look stock. They'll fool 90% of the people at a car show. The Edelbrock heads are flat on the end but even that will fool most of the people if they are painted engine color. If you have an alternator and a PS pump then very few people will ever notice the Edelbrock heads. There is a lot of information available on this subject. Go to Amazon.com and search for Mopar big block books. You'll find several on the subject. Spending $50 on books now could save you a lot of money later in the project.
