Stock 340 Manifolds or TTI Shorties?

When I was young I loved headers. Put up with the continuous gasket leaks, lack of spark plug access, difficulty in changing starters, burnt spark plug wires, smashed tubes; I was young. Now, everything I have has the stock manifolds. Your priorities change over the years.
You are right, and I too have been there. The big difference here is these headers are the shorties. The long tube headers were the real pain for me. These headers have great plug access and should provide good clearance to the (mini) starter I have. I have done so many engines in the past that I do not recall specifics, but I used Hedman a lot back in those days. We have options today that were not available back then. For that I'm grateful!
