I did the MAF conversion on my '87. The only thing different I remember doing is having to plug the MAP sensor port, easily done with a vacuum plug. Other than that, you have the canister purge port, the EGR/Thermactor port, the vacuum tree port, the PCV port, and the fuel pressure regulator port. Hope this helps.
