one set of lt1 heads. heads have a fresh valve job, cleaned, with stock valves and new seals. Come with cm 612 springs already installed. One bolt hole will need to be re-tapped. That's all the info I have on these. It looks like the exhaust ports may have been ported slightly, but I do not know the details on that. $300 shipped to lower 48
