I am working on a project and am researching bore refinishing and piston to bore clearances. What can the assembled experience here tell me about this topic?

I have found a business in Wisconsin called Millennium that replates bores with a NiSiC (like Nikasil) and hones the bores to match your pistons. Some of my questions:

Anyone have experience with this replate process?

What piston to bore clearance is speced by Porsche with Nikasil bores?

Can Alusil bores be replated with Nikasil? (I haven't asked Millennium this as yet).

What other experience/suggestions/knowledge can shed light on this issue.

Thanks
