I realize there are probably only about 4 people here that have any interest in this, but it's winter, and a little slow, so it's a small contribution......

It's pretty common for 40+ year old heads to have visited the machine shop before they find their way to me, and I'd say these had been there at least twice before.
They weren't really great candidates for HP heads on a stroker build...... But they are T/A heads..... Going on a real T/A car.
I don't have any idea if these are the original heads for the car or not.

At one point they had ex seats installed. Unfortunately they used the wrong size insert(too big), and sunk them a tad to boot.
They are big enough on the OD that the intake valve actually sits on the ex seat insert where the two valves are close to each other, so when you sink the ex seat, you then have to sink the intake valve as well.
Notice the "high flow" step from using the incorrect seat ring.
Real nice guide work too.
