I was originally going to run the factory heads and port them. They were 596 castings. After having discussions with several people about doing some serious port work on them, I seemed to be money ahead by buying bare performer RPM heads. I sent them to a shop to be set up and ported. Pretty sure the chambers can be brought down to the required size with those heads. Pushrods are going to be custom and the intake won't fit without some work. Not worried about that. More worried about whether the heads can perform as well as I want them to. There just aren't that many good options for small-block Mopars that don't get into some serious money. I considered used W2 heads, but I couldn't find headers would work for my Duster. I looked at cast-iron Hughes heads but they've been out of stock for a while. I've read about the Trick Flow heads but they never seemed to materialize. So I decided on the Edelbrock heads. I don't think 10 to 1 will be a problem. My last car was 13 to 1 and if I wanted to go anywhere I always had to carry cans of race gas in the trunk.
