Thanks for the reply Phil and apologies to Mike for getting off the track in his post.That movie clip was an eye opener to manufacturing processes in those years.
The heads are off on the 4 engines I have. Some for many years. Some studs are broken and not one seems to want to screw out. There are 2 blocks that are candidates for rebuilding so I have to be very careful with those.
I will start a new thread on the subject.
Cheers,
Terry
