Thnx for answer

P.S. i need an answer before tomorow 5 PM because im gonna buy this intake!!!

 

Well, im not 100% sure on what you are meaning by 4 vacuum ports. However, all critical hook ups are supplied. THere are provisions to hook up the brake booster. Sorry i could help better there.

The only problem i can see is the intake bolt pattern. in 1987, the intake bolts were changed up so that the center 2 bolts on each head were angled differently. SO unless the intake was designated for 87-up, the intake will have to be drilled out, which isnt that hard.
