No idea on cc, heads were surfaced only to clean up, and I have no idea what the springs were installed at, I’ll have to check a few ASAP and post that. As to The cc’ing of these it is up to whoever buys them to check. Keep in mind these are purely stock reconditioned heads only with some stronger springs and retainers for a mild cam. They were removed from an 87 318 that had never been apart. Only one surfacing, and one valve job so they aren’t sunk, and have oem style umbrella type seals, the guides and spring seats have not been cut/machined. No cracks or repairs, I started to plug the air holes in the exhausts but only got two done so those need to be finished plugging.
