12 Second N/A Slant 6?

So this has got me thinking about building the most wild naturally aspirated slant six. If I had unlimited money and just wanted to do something crazy I would...

Lighten the rotating assembly
Have custom rods made
Have custom pistons made
Port and polish the head and use the biggest valves possible
Use a very healthy cam
Machine the head and block so it was 12.5:1 compression
Build a sheet metal intake that would mount two 325cc 2 barrel carbs sideways (like the ones that come in the six pack setup)
Make the intakes so one carb feeds the front three and the second carb feeds the back three (would use a balance tube between the two intakes)
Build custom headers
Tune it and run it on e-85 and try to get it to rev to 6500-6800rpm

Now I just need about 8000 bucks, a Cnc machine, a tig welder, good machine shop, and a lot of free time. (Plus a hundred different things I am forgetting)
