Clifford intake is $320 and the short tube headers are $340...A good looking valve cover would be the offenhouser...runs about $189 from summet I believe. All are worth the money. I have a clifford intake and headers and 600 cfm edelbrock with a 60k distributor and it runs great...dual exhaust...Flowmaster 40 series mufflers...sounds really good after 3000 rpm!
Here's a vid to give you an idea.
