I am considering going with some vortec heads and a vortec intake designed for TBI systems. the GM site says "To use EGR, the gasses must be plumbed from the exhaust manifold into the intake manifold. Many exhaust manifolds have drilled and tapped holes that can be used to fabricate a tube. " so.......... I was wondering if just drilling a whole in a header tube and welding a tube will work........... HAS ANYONE used vortec heads and intakes with a TBI system?!? please help

 

yes several people have but they did it before the vortec tbi intake came out. They used carb intakes with TBI adapters on top.
