If I understand correctly, 460 heads did not change from 73 up untill the mid 80s. Then changed again in 93. Yours should have 97cc chanbers and 1.73 rockers. These heads are said to have .100" shorter valves due to the valve seats being set deeper. You can look them up easily, heres my source

casting-numbers-descriptions-1-index

Your heads are

D3VE-A2A

D is the decade where D = 1970s
3 is the decade year so 1973
V is the Vehicle it was designed for where V = Lincoln
E is the engineering group where E = Engine

A2A is the part number

For the block, its the same code scheme

81 Lincoln blocks, i'm not sure the significance of the 6015 on the first block, its a part number of some sort.


Hopefully this helps and someone can add to or correct any of this info

ok so that means that the blocks are 71 right? and why do they both have 73 heads on them if they are 71 motors? any ideas.

Excuse me, yes, 71 blocks not 81 like I wrote. If I had to guess, the motors are out of vehicles later than 71. If I'm correct, Ford designed castings and stamped them with the year they were designed, not necessarily the years they were used. For example, the E7 head was designed in 1987 but used on a lot of different years up to the 90s.

My guess is that the blocks were designed in 71 and used throughout the following years. The heads were designed in 73 and used up until the early 80s. Your motor could be out of a lot of different "Model years" as far as the vehicle go, but the motor would be the same.

Like, one motor could be out of a 75 Lincoln but still have a 71 block with 73 heads. At least thats the way I understand it! Are these original motors that have never been taken apart?
