I need a Poly top end

So this customer calls me up, and says she needs help.
She had another fellow recondition the engine,in her 67 Belvidere, and on it's maiden voyage, it bent 6 rods. No problem said I, I have teener rods.And oh, BTW the intake and carb are missing. No problem said I, I have teener stuff.
So this car shows up.
And it's not bent rods; it's bent pushrods. And oh BTW, it's a Poly 318.
The VIN says 318LA, The body plate says 318Poly, and the second owner says she's sure the poly is original.
So this other mechanic took the intake off, and the bent "rods" and 4 lifters out. Then he went to jail.
Lady get's her car back;minus all the parts.And 4 years later,he's still in jail.
And I can't find any parts locally. So here is my dilemma;

I need everything from the china walls up,minus the air-cleaner, plus 2 valve covers, and 6 pushrods, and 1 headbolt.(67Poly 318 ).

So can anyone help me?
