NON ZR-1 Magnesium Head Question & Cam Manufaturer

[limey]

You guys always give good info, so here we go:

I have a magnesium head that the intake cam seized up and damaged the head.

Parts are STUPID money $19.7 k for a BARE head & $6.5k for a cam.

Question:

Who can fix Magnesium heads?
Who can make a camshaft?
