Therefore, go for a 14mm thread size to use with performance heads. Another significant part of the spark plug is its gasket or washer seat that is positioned onto the mating surface of the cylinder heads. Finally yet importantly, you must use a hex that should be 5/8" in diameter to bring out best clearance. Tapered spark plugs can result in crushing the threads in the cylinder head thereby causing several mechanical problems. Therefore, avoid using them.
