Actually, mine seems to have the opposite issue, since I went with ceramic-coated headers (Hooker Competition ceramic-coated long-tubes, actually). I've used several different laser thermometers pointed at various different points on the engine and exhaust system while idling after several minutes at a time, and expected to see temps in the '400-to-600-and-above' range on the headers. I've never seen anything close to that. I think on the end of the tubes right at the mounting surface of the head - where you would expect to see the highest temps, I might've seen temps in the 250-270 range. Seriously - nothing ever higher than that... on the headers, no less! I was concerned with the higher temps of headers, especially since it seems like the starter gets a little bit of heat soak after running awhile (it has that little stutter when cranking, like the battery just ran down to zero for a split-second, then it cranks right over). But aside from that, I have no evidence that my engine's running any hotter than it should be - ever.I agree, if i could do it again, lizard skin would be the way I would go. They also make a spray on ceramic heat shield that you can go over the lizard skin with. These cars need all the heat shielding you can get, especially if you run long tube headers.
I have the same ceramic coated headers and the other day for the first time had the same issue you had with the starter. At first it stuttered as if the battery was low and then it cranked right away. I have a hi-torque starter as well which is smaller and it is more separated from the header. I may have to add a heat shield in the area.Actually, mine seems to have the opposite issue, since I went with ceramic-coated headers (Hooker Competition ceramic-coated long-tubes, actually).

But, you are correct that any and all heat shielding is a good thing. ::thumb::
