First 2000 or so engines.
But it has a spark plug broken off! It has been like this for years and needs machining.
Broke an easy out, years ago trying to get it out!
But I am going to sell this core when I fix the plug hole.
All others are good.
Just wondering the value like it is or totally redone with a $500 dollar bill from my machinist
Or just the core with the plug hole fixed?
Either way I am selling it on ebay. One sold a couple of years ago NOS factory for $1800
Thanks for any opinions.

You can see the broken plug in the hole middle plug to the right
Can anyone find a picture of the vacuum nipples that are used on this early head?
Can't see it in the manuals I have
I see one on ebay now with a broken fin and 2 broke exhaust studs, selling for $455.
I am sure they are brass, This current ebay one shows them straight.
But I recall a set of NOS on the bay years ago, they looked bent, with a 135 degree angle.
I fixed this head's plug.
want to finish it up.
Thanks for any information.
