Fuel Injector O-rings and Washers Musings 1800 1970

Got all new seals for my injectors. Noted some interesting things.
2 of the holder o-rings were cracked. All were very brittle and flattened. They didn't even look like o-rings, but more like washers. All the holders were very grimy on the inside. Also, there were no fiber washers. So, after all new o-rings, started up, and didn't run as rough or die during warmup. Could it be possible that I had some air leaking past the holder o-rings, causing the roughness?

What's the purpose of fiber washers? Do they aid in sealing? FYI, there a 2 fiber washers. One goes between the injector holder and the head. The other goes between the metal washer and the holder. (My metal washer was still there)

The fiber washers prevent heat transfer to the injectors thus preventing vapor lock.
