Extrude hone exhaust manifolds or not

A lot of money for very little gain. Just make sure that your flapper in the pass side manifold works and put them on. Either that or headers. But you probably want to keep that stock look. I have the Schumacher headers on my duster (big block) and they are almost like tubular manifolds. As much ground clearance as stock, they weigh less, and have to be some kind of performance gain. Don't know if they have something like that for small blocks, if you're interested. As far as the intake, do not touch the inside of it.
