Reading Plugs

[timsiford at hushmail.com]

I am currently in the middle of replacing the head gaskets on my car while 
she is down for the torque converter swap.  I finally pulled the plugs for 
the FIRST time since I installed heads/cam back in late 1999.  Yes, the 
plugs have been in the car for a full year.  In that year's time I only 
put about 3-4000 miles on the car.  Anyhoo - I used the websites previously 
posted on the list for comparing plugs:

I couldn't really find a pic that looked like my plugs.  They don't look 
as black as the 'rich mixture' plugs but they definitely don't look as white 
as the 'normal' plugs.  However, what I am noticing is orange.  Yes, orange. 
 The insulators are very orange.  Take the 'normal' plug, cross it with 
a rich plug, and then paint the insulator orange.  Wierd.  Never really 
seen a plug look like this before.  I am borrowing a digital camera to take 
some pics of my work progress this weekend.  I'll make sure to snap some 
of the plugs.  
FYI - these plugs are Bosch Platinum +4's
