Modelle, Yes, you can replace the seal without pulling the head. If it was my car, I would remove the remains of the old seal, put it back together, and go enjoy the convention. Many old cars never had seals, and the ones that did had a simple rubber boot type seal that would fail in a very short time. After you get back from the convention and have a replacement seal you can remove the plug for that cylinder and stuff some rope in it to keep the valve from dropping in to the cylinder. Remove the camshaft and follower and use a spring compressor to remove the keepers and extract the spring. Install the new seal and put it all back together.
