my header cracked at the #1 and #8 head flange.
A guy at the track gave me some of this stuff to make a temp repair last year.

I forgotten all about welding the flanges and realized i been driving all over the place and doing launches etc.
Man this stuff works great!
if you got ceramic headers it dries to the same color and shade? ( my header is dirty in pic)
I saw the guy yesterday and told him how great it is.
he also uses it to repair pitted ceramic headers.

Nice!

Now that is good to know!!!..it does look good....

and i just threw it on . (see the front header bolt lol)
I bet if I took my time it would be almost invisible.
and why is it that unless you get custom made headers they all weld only the inside of the primary tube to the flange?????
