Stock Piston Question

I've been doing research on the factory specs for the 2003 4.6L SOHC engines and have not been able to find specs on the pistons. I know they are dished, but how much?
I'm also looking for:
Head chamber volume
Head Gasket Bore
Head Gasket Thickness
Piston Down Bore TDC
Deck Volume @ TDC
Volume above Piston

Once I have finished collecting info, I will be willing to share.

Thanks
