Hello everyone. I need some advice on heads. I guess i am looking for a quick education. I want to put this 400 block in my bird. I do not have heads for it yet. I eventually want to put edlebrocks on it. My goal is 400+ hp. Now the question is i don't have the funds to do this yet so i would like to put some factory ones on for the time being. What do you recommend? I have seen alot of 6x heads. like i said i do not know alot of what these are. I knkow the workings of heads and how to assemble them but nothing else really. I ahve also seen 6x-4?
Please help. I thank you for any input you may have. I also should say that this is going to be a cruiser engine that eventually will melt the tires on command . Thanks again
