I have a 67 chevelle w/ the original 283. It has been rebuilt once and bored .030 over. It has the original heads on it and I would like to change the heads out. My question is, what heads should I get, keeping in mind I would like to keep it cheap. I have done some research on here and it seems like a 305 truck head is that way to go. I was thinking of get a set on ebay or somewhere else for cheap, then getting a rebuild kit and fix them up. Any opinions on this?
