A carb'ed 86? That would be a firm no imo.
I'd do a factory style maf upgrade if you have the original parts in place, if not I guess you could do something like a holley terminator. The heads will be a crap shoot. For sure you will be checking clearance, but with an 86 you may be doing so for any head other than a e6. Will the heads work well? Again, not sure, most well running and performing engines use proven combinations that work together.
