Yep. Move on. So I'm in a similar situation
I have an original '70 350 runs great. Previous owner took the heads off and sold me the truck with '78 smog heads on it. He was upfront about it when I bought the truck and since become somewhat friends.
I don't want aluminum and going to buy these cast heads from summit racing. They are made by Dart and seem like a good value.
Mine truck or just a nice driver. Gets up and really goes already but I want to put better heads on it next winter.
Cool thing is summit racing in Ohio is 40 min from my house. Not sure if free shipping applies to heavy time such as this.
