I take it you want to paint your exhaust manifold?
Try using some high-temp barbecue paint. Most of it is good until 1,300° of continuous heat, which is a perfect rating for using it on the manifold. I painted the manifold on my '98. 5, and it held up great. The product I used is called Stove-Bright, and is available at Lowe's for about $3. 49 a can.
