I got two sets of A heads with the 442 I just bought, do these cylinder head numbers match up with either the VIN or numbers on the engine to verify they came original on the car? Thanks in advance, Tom.

 

Won't match the VIN. Did the car come with P-O-P by any chance?

 

Unfortunately no, no build sheet or P-O-P.

 

That is the engine unit number and the original P-O-P will have that number and the trans unit number along with the VIN, allowing you to tie all three together. Of course, that only proves that one cylinder head is original to that car. Without the P-O-P, there is no way to link the numbers.

 

Thanks Joe, I appreciate it.
