Where on the head is the casting number that show what series the head is e.g. "D1VE"?
I have a 460 with the heads mounted to the block and I looked all over and cant find a casring number. The only numbers I found were some digits by the #2 cylinder valve springs.
Side note: Im looking at buying a 1973 police station wagon with a 429. Id like to look it over to see if it has the police interceptor heads but I dont know where to find the casting numbers.
Thanks

 

Does anybody know?

 

If the heads were cast in the '70s (and possibly the early '80s), it most likely will be a D3VEA or similar number. D2VE, D0VE are common early '70s numbers (stay away from D2 heads, by the way.) It will be between the spark plugs.
If the heads were cast in the '80s, the numbers will be on the underside of the head, on the lip that extends past the block and over the valley.
If the heads are off the block, turn them upside down and you will see them.
If they are still on the block and you have the intake off, use a mirror to read the lip, the underside of the heads. I used a dental mirror.
Good luck!

 

Ah ha! Thanks for the reply. That explains why I couldnt find the number on a complete motor. And just FYI I won the auction for that 1973 police station wagon for $150.

 

If it has the actual police interceptor engine, the one exception to the; stay away from D2 heads is the D2OE heads those are the police interceptor heads and rank right close to the cj, scj heads.

 

MB: Thanks for clearing that up. Glad there is someone to clarify my goofs!
