I've got a TBI 350 and the intake had to be modified slightly to bolt on to the heads - I'll get a pic in the next day or two...also, make sure the casting number is 10239906 and 12558062, as these are the Vortec heads you'll want.Idk if anyone makes a vortec TB to carb adapter. If its the same base plate pattern as the older TBI then yes you can use it. Really the only other thing you would need is the passenger side exhaust manifold if you want to retain EGR cause the vortec heads dont have crossover.
85Frankencar said:I believe (correct me if I'm wrong) GM started using the Vortec heads on 96+ trucks - Edelbrock & Holley make aftermarket intake manifolds for carbs to run Vortec heads (along with their own aluminum version of Vortec heads) - there's several different styles, check out their website, it'll give you more specific info. The old-style manifolds are not a direct bolt-on, but again, correct me if I'm wrong.
