Pre Chamber inserts on 1210 or 1310 head

[HurriCain]

Well, Got my replacement engine home and decided to do a leak down test on it before putting back in tractor. Went to spin motor over with strong arm and would only spin 3/4 turn in each direction. HMMMMM. Pulled head and found a pre chamber insert had fallen out of head and lodged between head and piston. Thankfully, I don't think motor was run that way as no signs of crushed chamber in top of piston or head. Now, Where can I find replacement Chamber inserts? TIA

Used head probably the best option

How that saying go? I respectfully disagree. Can't see why it would be necessary to waist a good casting head simply because of a pressed in heat shield in the head for the injector. I will post more once I find answers but I'm fairly sure that there is a repair option for this head.

Shibaura does/did not supply Chamber inserts separately. I've been through this problem before.
