318 budget/low buck build.

I couldn't read the first post. To lengthy for my tired eyes, but as far as a "On the cheap" 318 build, click this for my veiw; http://www.forabodiesonly.com/mopar/showthread.php?t=10508

A "Inlet" or intake manifold for 5500 would be a;
OE iron 4bbl
Edelbrock Performer
A old Edelbrock LD4B
Weiand (Say Why-and) Action Plus intake manifold. (Up to 6,000 rpm's)

The head would be based on how much power you want to make along with being coupled with cam and axle ratio.

What is the HP goal?
In what vehicle and weight?

Look in the for sale area here for a Performer or such.
