[Focus man. Focus.]

I had an 85 F150 with a 300ci in-line 6 bored 60 over with a steel straight cut gear drive and Mac headers. I was getting a lot of heat into my starter and it was so bad my truck wouldn't start after a short drive. I bought a header wrap kit and was going to do the headers. Yes there were 2 headers, 1 for the front 3 cylinders and the other for the back 3. But after hearing stories about header failures and gasket replacement problems I decided againts wrapping them. So I wrapped the starter instead and bought a 1000cca battery. Problem solved.
