yeah, I think glossy headers look good if they are plated real nice, but not with regular old paint, the flat look came out pretty good.
I got my can out of a Jeg's catalog, it was a long time ago, but I think I looked up header paint or something similar in the index. Regardless, the brand is VHT and it has "1500" written right across the front of the label. There are several choices for finish (gloss aluminum, gloss black, silver, etc) but I think one of them is "flat black" or something of the like.
Make sure you don't get regular old engine paint, the header paint is made to withstand far greater temperatures.
