Default TBI vs. carburetor manifolds.

I have a early 90s TBI motor that I want to put a carb on. Do the old school carb manifolds bolt right up?

Note: This engine will be installed in a project and I don't have any of the computer goodies, so carburetor it will be.

you can put the old intakes on the `87 and newer heads but the center two bolts are 15* tilted up. I have always just drilled the holes bigger and used an old rocker ball on the bolt to equalize the load when tightened. if its not a show piece then its a no brainier, its a show piece then buy an intake that has the correct bosses machined into it.
