you need a special manifold to bolt the tbi stuff to the vortec heads because the bolt pattern and ports are different. you will also need the left exhaust manifold&egr from the newer engine if you want to hook that stuff up. i know gm performance parts has a manifold to do this conversion but it's very expensive.
