Re: Header or Not To Header That Is The Question

Headers can cause problems with starters because of heat soak. If I had to do it again I would have not gone with headers on the 454 in my '71 since the engine is more or less stock.

The engine will not turn over when the engine is warm because of heat soak of the starter. After it cools off it turns over ok.
