Heads were installed for approximately 2,000 miles. I bought these from a vendor Sperry Engines on Ebay a few years ago. They were cleaned up, new z28 springs installed, SS valves, they had a skim cut taken to ensure they were flat and true for installation. I installed them with the GM .028 head gaskets on a stock 1986 short block.
I'm installing a 383 so I have no need for these.
I'm in New York and a local sale would be preferred but I would ship at the buyers expense. I even found a box of new a.c. Delco spark plugs that will go with the heads.
Asking $400/plus shipping

Thanks
