Those heads might be worth that if they were pertinent to the original, first 135 CJ cars. After that, not so much. They certainly could be unmolested originals. They have value to collectors and restorers. Maybe closer to $1,200 if they are in very good condition. Any flaws, like corrosion, needing a valve job or other machining, then the price keeps falling. The problem is the market for them dried up once the aftermarket started cranking out Medium Riser alloy heads.
