clever! thanks tom! I was confused because competition engineering's page lists the following machining options:

Modify 911 heads for dual spark plugs (includes drilling lower valve covers) $ 400.00
Weld up original 14mm plug holes and machine for dual 12mm spark plugs $ 750.00

of course there's more than one way to skin a cat...
