1970 340 engine

Hope this helps...these are from the seller, and he wanted to pass along that he needs to sell quickly if at all possible.

Edit: I forgot to mention these are X heads according to the seller, the valves clearly need set, he said he's not sure what kind of cam is in it. It it used to have a single plane intake, and when the intake was swapped, the lifter valley was clean. Also, the oil pan has been replaced since he bought it...old one was rusty.
