Let me know if you need a set of those Dart Sr.'s as I have a friend who has a bare set he is selling for $470+shipping. They are brand new and unused. Email me if you need more info. Thanks!

Hey Walt, what problem with the exhaust ports? I have a set of Jr's do these have some problem with them too?

That exhaust port problem only exists on the later model Roush 200 and 180 heads. The earlier Sr. and Jr. don't have that problem. Strange how they went backwards when designing a new head with Roush's name on it. Somebody got fired for that one, LOL!
