Ported Slant 6 head

I have no worries on the carb. Since it's vacuum operated, that means it is limited to the RPM it sees, and will only pull the secondaries open at the proper RPM. Of course, as tuneable as the Thermoquad is, I can have a serious influence on that, but tuned RIGHT, the secondaries will open when needed. Of all the things I'm worried about, the carb ain't on the list. A stock 318 will suck the guts out of an 800 Thermoquad, so I am pretty sure my hot little slant won't have any trouble either.
