Hey all,
I have a Ford Racing 347 (2004 vintage with Z heads) with a ITB intake set up.

I noticed a rough idle, changed the plugs, followed by a compression test which showed zero in numbers 2 and 3 cylinders and readings pretty much all over the place across the board.
I pulled the heads and discovered what I suspected - a blown head gasket between 2 and 3.
Further inspection revealed the following:
Head 1 - Damage between 2 and 3 chambers. 
Intake manifold - Pitting from water/coolant leaks at each end on both banks.
Bores - Pitting from water/coolant sitting in a couple of cylinders. Fingernail sized.

So my questions are:
Will a Hone remove the pitting alone?
Given the 347 is already 30 thou over is this block junk if it needs boring/honing?
Will a machinist be able to surface the heads and intake to match correctly again?

Thanks heaps in advance.
Steve
