I am working on a 66 442 convertible, 4 speed. The heads that are on the motor are A heads with V010350 stamped in the end of them. Could these be correct if this was a early production car for 66'. If these are not correct are they 442 heads. I have a set of B heads also and thinking about getting them reworked. Not sure what they came from. Is there anything special that needs to be done to them.
Are the A heads worth anything if I sell them?
Thanks for the help,

Those are not 66 442 heads. They are 65 442 400 heads with that V0 #. A heads didn't come on a 66,only B heads but some 65 442 cars had B heads along with the A heads. 66 442 400 B heads had a V1 # for the engine prefix.

are B heads a direct bolt on, I read somewhere that the push rod holes may need to be drilled bigger. How would I know if I need to do that.

Also how do you figure out the date stamp of when these were made.

I'm not sure what you're asking about direct bolt on to. All BBO heads interchange. The 65 400 engine is a 45* bank angle & the 66 400 is a 39* bank angle. Since 66 used the B heads and some 65's also did,I do not think the push rod holes need work. Unless the 65 B heads had the push rod holes modified for use on the 45* block,they should work. Maybe somebody who has done this will chime in. The Julian date is on the raised tab above the #2 or #7 exhaust port. It has 2 screw looking heads on each side of the date.
