68-70 all 4 holes are the same, Thats know as a square flange intake, Yours is known as a spread bore where the primarys are smaller than the secondarys.

Thats not a spreadbore intake. I made the same mistake once. The 68-69 squarebores had slightly larger secondaries. Spreadbores are MUCH larger.
That's correct. Those intakes do have slightly larger secondaries. Even so they are still referred to as square bore. If you wanna know why, just look at a Thermoquad intake. LOL
