I am using RV8 headers with POR-14 High Temperature paint, which is
advertised to withstand temperatures up to 1400°F. I haven't noticed any
signs of overheating on the headers or any other components near the
headers. That includes the inner fenders and engine. I don't think the
paint is providing any type of heat shield but I am using an engine driven
fan, which is keeping the air moving across the hot surfaces.
Did install a heat shield over the wires going to the starter just to be
safe. Didn't want to melt the insulation on those wires. That could start
a good car fire and I am not into that.
On a side note has anyone else posted pictures form this years V8 meet?

Hello all,
Does anyone have a reasonable estimation of the temperature the exhaust
reaches on their V8s? I am particularly interested in temp near collector,
and the temp at any other place in the exhaust pipe. As many of you know my
headers are going out the fenders and through the rockers and now that they
are built I am investgating how much heat sheilding I will need, and if any
special paint will be needed on the rockers to keep from burning off.
The exhaust would be done too, except I got held up when my thumb had an
intimate meeting with the business end of my hacksaw.
