360 Heads very good condition!

I would say they are pre 77 heads. They have the bump and area for the egr, but are not drilled for it. I had a set of 77 heads off of a truck that had the egr drilled and I had to put set screws in them to block off the egr. My guess is 75 or 76.

Thanks for the larger pics. They look like nice heads.
