If they are the original seats the answer is no.

Johnny, they were all deep hardened after about '73 or so and it is a hit or miss deal from about '71 to '73 if I have this right.

Therefore you can go over to Mortec and check out which years the heads were used and it will give you a better handle on this..

But you will need the head casting number.
