The 87 intake will work wiith modification to the center bolt holes. If the 86 intake is from a TPI just use that with the rest of your parts. An 86 vette should be TPI and it coud have aluminum or iron heads.
If the intake is from a Crossfire inj vette it would be an 82 or 84 and that intake will not work with TPI.

I'm not sure about the iron heads, but the aluminum vette heads do not have an EGR passage. You will either have to run a pipe from the exhaust manifold or header to the intake, or eliminate EGR from the chip(PROM).
