Great work and thank you for you sharing.
On a side note, and the wiz in here can comment on it, I was told, long a go, that redoing the valve on an older car may put too much pressure on the older connecting rod causing some major problem.
At that time I did not want to believe it, so when my son's Chevrolet Cavalier threw a bent valve stem I re-did the whole head. ( By the way that nice finish on the head is a " Glass Bead blast)
After the work the car ran great. No shaking and the cylinder pressure went up to 185-190 from 160-165.
It was only about 1 month later that I had to eat my crow, when the car blew a connecting rod. Luckily the block was not penetrated but it messed up the crankshaft. After a complete rebuilt the car ran like new. Too bad , while parked in a HOME DEPOT parking lot someone ram it so hard to cause the insurance company to total the car and this only after 2 weeks after the rebuilt.
I do not know if this is something typical of American cars, or if only happens on car with a lot of mileage I'm not sure but would be nice to gather the experience of other in this case ..

I hope that doesn't happen, thanks for your input. I will just have to keep my fingers cross.
