Delet thread, head is gone, thanks

I have a clean, not cracked or warped cylinder off the Chevrolet inline six. It has had the guides replaced, 1.72" intake, 1.6" exhaust valves which look all good, 3/8-24 poly-locks, no springs. It will need new exhaust seats or some creative machining. I ran it for a number of years till it started acting weird, I replaced it and never looked at it. Pulled it out this week for a clean up and inspection, found the exhaust seats bad. Can send pictures if interested. Free for the taking.
