Well, I was just at the hardware store researching fittings and copper pipe, was thinking of a small 3/8 pipe from the exhaust mani and running along the inside of my homemade block-off plate or easier yet running in on the outside of the plate and hoping it heats up the chamber in the manifold that is leaking.I have fenton exhaust headers with the pipe threaded holes in each one. Maybe I'll just block of the chamber and run w/o heat. It ran that way when my dad owned it for 20 years
