Is it possible to run a stock GM manifold with Fenton headers without heating the fuel. I understand why a stock exhaust manifold heats the fuel on a cold engine, and closes on a warm engine. I really do not want to remove the headers and stainless exhaust, but if the prevents me from having a smooth running engine I will remove it. I purchase a new stock exhaust system from Waldron's in the event I cannot run the system mentioned above. The average winter temp here in SW fl. is 75-54 degrees. and in the summer just hot.
