head identity help
Hello everyone....Can anyone help me out? I know you can...but WILL you please? I have a 460 with a set of heads on it that I have no idea what they are. The heads casting numbers are as follows: D3VE A2A Anyone know anything about em? If memory serves me right, they are at least 1973 heads? Are they open chamber? or closed chamber heads?
Thanks for your help in advance guys....I will now go pay hommage to the Ford Gods in thanks....hehe

Sorry about that, I forgot to address the second part of you question. The '73 heads were not really a closed chamber design like the 68-71's were, BUT they were also not the big open chamber that the '72's were either. I would describe them as an "opened up closed chamber" for lack of a better description. They had a combustion chamber volume of around 95 cc's. The '72 heads had a volume of around 90 cc's. Even though the '73 heads had a very slightly bigger combustion chamber, the heads offered a bigger quench area, which helped to reduce some of the detonation problems that were inherent in the '72 design. The 68-71 heads had a much smaller volume of about 75 cc's. Confused enough??
