The intakes are slightly different.....I think the intakes for the 1992 and 1993 models are specific to the intake because they have a groove at the top for a crossover line.

With the heads, I know aluminum heads were put in corvettes, camaros, and firebirds. I intend to send them off to Eportworks so does it matter what kind of heads I should be looking for? Specifically corvette heads or the 10128374 as described?

But for each year the LT1 was used, the Corvettes and F-bodies had exactly the same castings.
In other words, there's no such thing as 'Corvette heads'.

Its not just the 374's that are good for porting. The 643's are also very good for porting. Those 2 are the desired casting's. The 561's are the late 96 F and Y body heads and 97 F-body heads. As mentioned they flow better in stock form. Any intake will work on your single crossover tube setup. If you got a later style intake you would have the unused extra grove for a 2nd crossover. But it will still work.
