Cylinder Head Casting Date?

It's the head that goes way without hard seats and not the valve. You won't have any problem without the seats if it is a part time car. It is on a daily driver that the seats will start to go way. The easiest way is to measure the intake valve to tell which one you have. Most 915 heads were 1.88's. T/A 915 heads were 2.02 and I have heard that some non T/A heads were also.
