Header to sidepipe flange Gasket material?

[Whaler]

Hi Jim I am thinking about the RTV bead if the metal solution is "undoable". Sounds easy as it is a gasket maker.

On deadsoft etc heres a bit of info

Dead Soft Annealing
Heating metal to above the critical range and appropriately cooling to develop the greatest possible commercial softness or ductility.

Dead Soft Steel
Steel, normally made in the basic open-hearth furnace or by the basic oxygen process with carbon less than 0.10% and manganese in the 0.20-0.50% range, completely annealed.

Dead Soft Temper
Condition of maximum softness commercially attainable in wire, strip, or sheet metal in the annealed state.

Now as my builder had said he mentioned sheet copper...so

" Copper
This metal and its alloys have many desirable properties. Among the commercial metals, it is one of the most popular. Copper is ductile, malleable, hard, tough, strong, wear resistant, machinable, weldable, and corrosion resistant. It also has high-tensile strength, fatigue strength, and thermal and electrical conductivity. Copper is one of the easier metals to work with but be careful because it easily becomes work-hardened; however, this condition can be remedied by heating it to a cherry red and then letting it cool. This process, called annealing, restores it to a softened condition. Annealing and softening are the only heat-treating procedures that apply to copper. Seams in copper are joined by riveting, silver brazing, bronze brazing, soft soldering, gas welding, or electrical arc welding. Copper is frequently used to give a protective coating to sheets and rods and to make ball floats, containers, and soldering coppers."


Sounds easy enough. Heck if the flange surface is less than perfect why not do both? Use a metal gasket and supplement it with RTV?

Jim can you apply it, bolt her up and drive away, or should you let it cure??
