Hemi head identification

No, it is a rebuilt engine. It is built for drag racing. Already has manifold and carb on it. Supposed to have a .600 or so lift cam in it. I didn't have any tools with me to measure the lift. I don't think these are the stock heads on it. I have done a little research on the numbers and I thought they might be eagle heads, not sure though, I think they may have changed the eagle head numbers. Thanks Mike
