Gosh, I'm glad I asked. Now I feel educated and thanks to you guys for taking the time to do so. I appreciate all of you!
However, I have one other question so educate me some more....
From what I'm reading and learning here most of the thread seems to be centered around the 1958-1962 engine. What about the early 261 engine like my 1956.
(my engine is not in my shop right now so I can't look at it for any obvious answer). Does this question fit here or should I delete my post here and start another thread??
