I have a set of factory cast iron tunnelport C7OE-K heads for sale. The date codes are 8g15 and 8f15. They are in decent shape with about .020 thumbprint left. they look like they have been port polished but not heavily ported. They have the normal hairline crack from the sparkplug to the intake valve seat on two places on each head. $1000. Give me a call if interested or for pictures. 817-929-5551. Mark.
