Default Head missing digit

Just pulled the heads off my 69 and discovered that the last digit of the casting number is missing on one of them. One is 3927186 and the other one is 392718. I have searched and searched, cannot find anything about a digit missing. Just curious if anyone has seen this.

Well things happen at the foundry

If the valves match your other one and same or dated close, should be ok
Also the configuration of the humps at the back of the heads match then you should be ok
You must have the 350 350 HP
Other than that a foundry error in casting
