|You will have
to make your own Phenolic Spacer. They are usually only available
for the typical domestics and Hondas..
I have used this in the past: " .125" x 12"
x 24" Teflon(r) Virgin Grade Skived Sheet "
It insulates very well and has an operating range of
-400 to 500F. Low heat expansion, easy to cut, soft enough
that it will seal well between two surfaces. I used a
ball point pen to indent/trace the gasket (intake manifold, throttle body, etc.gaskets) into the Teflon, a drill, small project hack saw, and
a razor blade to smooth out the cuts.
Here is some info on different options
Good example of standard pricing for Teflon (choose "Industrial
Plastics - Sheet, Plate"):
Try an EBay search
for Phenolics to see if there are any deals on there.
Hope this helps ya. I have been using a 10" Coping Saw and Drill to get the rough design and a thin project razor blad to smooth out the cuts and perfectly size the phenolic gasket. If you have access to a water jet cutter, that would be the best method.
