Set of 452 casting BB mopar cylider heads. These heads came off running motor that had low miles on it. They were fully gone thru when they were put on the motor originally. they were surfaced, valve job, and guides and seals. I didn't have alot of miles on them because the car was barely driven much. Got a good deal and Replaced with aluminum heads. These heads would be great for a driver big block motor. Any questions feel free to email me.
