rebuiding T4 advice

[Newbie]

Machine shop said heads are too far gone.
Crank is good, still working on block, p&c.
They have rebuilt balanced rods for $65.

I'm planning on balancing everything.
Would like to get a little more Hamster power and MPG if possible.

So far needing:
Camshaft (webcam #?)
Lifters (webcam)
Rebuilt Heads for 2.0
Oil Pump (any recomendations)
Fan (mine missing a fin)
Intake Manifolds & linkage for Dual Dell's

Any ideas as to where I should shop for parts?
Trying to keep it low budget
