i need a set of spark plugs for the trick flow heads.. i used to have the ford motorsport 2 degrees colder on my old heads(stock) but apparently plugs wnt work on the new heads... anybody running these heads with a s/c what kind of spark plugs?
They fit, but they are too short and don't extend all the way into the combustion chamber. Plus the aluminum heads need plugs that include the washers with them. Putting in the stock ones may tear up the aluminum at the seat..
