I have a couple of questions about this early engine photo:
If you notice the line from the oil filter to the fitting besides the fuel pump is braided metal. When was this replaced by the standard rubberized oil lines and were both lines braided metal on the early engines?
The other question is the rear valve cover bolt. It has a post that sticks out about an inch or so beyond the bolt "head". What was this for? Toby Wacker showed me a repro he had made of this bolt and it has two holes drilled in that post that sticks out. When did this go away and replaced by the standard bolt.
