I have a crusty set of what my research tells me are late 65 400- 425 heads, part # 383821. There is a broken valve cover bolt in one and a broken easy-out in one of the plug holes in the other. Looks like they can be tanked and machined. Don't know if these have any use other than boat anchors. If interested, make me an offer.

 

383821 casting number is '65, should have a large A cast in head by spark plug.

 

That is correct.

 

Pics of them? Can send to 815-298-2912

 

Could use a backup set but too far away, hopefully Brownbomber can use them.

 

Sorry Brownbomber, I am the last person on the planet that doesn't have a smartphone. Here are some pics, if you need specifics, PM me for more. Thanks. BTW If interested make an offer, I really don't know what they are worth. I also have a forged crank #384722 for this engine.
