Dart Heads & spark plug wire clearance
« on: August 21, 2017, 09:24:32 AM »
I am in the process of completing an engine rebuild on a roller block. Specs are listed in signature. I bought and installed a new set of Dart ss Iron Eagle Heads with straight plugs. I bolted on my Flowtech headers that were on the previous Mr. Goodwrench 350 engine that had no clearance issues. Now with my Flowtech headers on The Dart Heads I cannot put the #3 spark plug wire on because the tube is about 1/16 in. from the tip of spark plug. I know I can heat and dimple the tube to make it fit, but am looking for a new and hopefully better built header for around $250-$300 that will have no clearance issues. I do not want to spend $300 and still have to pound header into submission. Any help would be appreciated. By the way, I am in my hometown,where i went to high school, this morning waiting for the solar eclipse to be its totality around 10:21.
