Just scored some complete heads at a swap. Casting # 3418915 H, with a "j" where the spark plugs go in. Are these Good heads,???. They have the valves, springs,retainers, and a set of 273 adjustable rockers and shafts.
I am going to build up a 340 this winter for my 66 Dart project.
I know they are 340/ 360 heads anyone have any more info on them,???.
Thanks Dave C.
