X-heads or J-heads on a 360 LA Engine

Part of the issue with documented one owner unomlested deals is in 1970 and on before these cars became collectible, nobody gave a rats *** about the heads on the car.

We had a 70 Duster 340 with an X and J head on it, december build. Another 70 swinger 340 with X's on it, October built car. Only reason I remember that, one of the neighbors was a Stock Elim racer and mentioned the heads on both cars to my Dad. The Duster ended up being a SS car later on and the Swinger met a tree or pole from the owners kid showing off. 1978-1980 buying a 340 car for 700-1200 or a big block 67-69 Chevelle or Camaro for the same. The good ole days. LOL
