Hello,
Can someone tell me what is going on with this little oil line that goes from the side of the head, back toward the rear, around the back, and down to the lower feed rail (dont know if this is the technical name for it)? I have seen pictures with and without this oil line.
Also, I kind of remember my grandfather telling me about the "crimped" supply tube sticking straight up by the rocker arms, but would like to hear reasoning on this as well.
Last night I looked up the casting numbers on the block and found it to be a 1961.

hopefully the picture links will work
