84 had L83 engine ; heads apparently the same as L82 76cc heads. Generally listed as casting #462624
Check your head casting # over at Mortec

Don't tell your buyers this from another forum;

"The 624 heads are among the worst of the worst. Don't bother spending any money on them. They are highly prone to cracking in critical places, and do not take kindly to port work as a result; their combustion chambers are a cavernous 76cc, and leave you with a compression ratio way short of anything resembling performance; and their flow..... well, they're part of the formula for building 180 HP 350s because they're so restrictive."

Good luck trying to sell them. If you can great. From past experience I've found that anybody trying to sell em can't give them away. Myself included.
Unfortunetly the heads on the stock 84's really aren't worth anything.
