[DeTomaso] Heat Insulation - Engine Bay

[John Taphorn]

I am about to reinstall an engine with 180s into the engine bay and 
would appreciate product recommendations for protecting the painted bay 
from heat generated by the exhaust pipes.

I intend to use a stainless steel sheet attached to the decklid to 
provide protection.  Any suggestions as to what to insulate the side 
facing the decklid?  I hope to have the engine bay facing side polished.

Additionally, I welded, prior to painting, mounting nuts on the 
underside of the decklid for attaching the stainless heat barrier. Is 
anyone aware of an insulated bolt/stud arrangement that would reduce the 
heat exchange?

Also, the header pipes do pass close to a section of painted engine 
bay.  The previous solution was to rivet polished stainless steel sheet 
over that painted section.  Is there another approach to consider?  
Perhaps a pipe wrap for those 5", or a space age thin layer of something 
that is impervious to heat transfer.

I've seen new products introduced from time to time; anyone know the 
latest and greatest?

Thanks
