Hey guys, I just got my first car a little over a week ago. It's a 1969 Buick Special Deluxe with a Chevy 250ci straight six and 3 speed. I'm coming here because the guys at the buick forums weren't of much help on a chevy engine. I really want to hop it up and the first things I thought were exhaust and intake. This version of the straight six has separate manifolds because I know the later ones had a combined single manifold. I have an idea on what to do. I want to get headers and run dual exhaust out the back and I was hoping to get either dual 2-barrels or a single quad along with the new intake manifold. How would both of these affect my mpgs/hp gain? And how would I know what carbs would fit what? Do all GM's of the same type (single, 2 barrel, 4 barrel) and time fit each other or what? The last thing is how do I know if I'll drown the engine or not? Its just got a single 1-barrel Rochester on it right now I believe
I was looking at getting...

Headers (what type of stuff would I need after the headers?) -http://www.stoveboltengineco.com/acartpro/product.asp?productid=171
Would I need anything else and would this be worth it? Thanks
