Here is a time lapse video of the valve stem seal replacement. I didn't have my Lisle valve spring tool so I had to struggle with the clamp style tool that I first learned with. Most of the valve seats looked good with the exception of the first two exhaust valves which I lapped a couple of times before moving forward. Also, I didn't have assembly lube so I used Vaseline to hold the valve keepers as I was installing the valvetrain. Stay tuned for part 2 and then the installation of the head gasket.
