Re: Headers, to wrap or not to wrap?

[pwatson@ix.netcom.com (Pete Watson)]

question.  I have experienced a nasty problem at the race track of the 
header wrap soaking up oil and gas leaks, and then becoming a large 
wick if it ignites.  It is also very hard to extinguish, as the header 
heat keeps re-igniting it!  This is probably not a good thing to 
encourage on a street car, which may be driven for a long period while 
oil vapors collect in the wrap.  I think a heat shield would be a 
better idea.
     I wonder if your crystallization problem was caused by the chrome 
plating.  I've heard that this can happen if the plating isn't done 
exactly right.  Any platers or metallugists out there?
