Hi All
My favorite machine shop asked me if I could help sell these. I don't know much about this vintage, can anyone verify these are 394, which year, and if the stamp is related to application?

 

Yes those are 394 heads. 1963 1964

 

Thank you for the confirmation. Do you know if the J 654785 stamp is the application, like the 64-67 engines have one head with a stamp on one end?

 

The J prefix stands for a 4bbl engine and not showing any postfix it should then be a 10.25:1 high compression engine also.

 

They are # 23 heads, the last design.

 

Wish they weren't clear across the country. FedEx guy wouldn't like toting those heavyweights!

64Guy, are you paying attention?
