90% of tight fit header applications require the use of shorty spark plugs
Note: not for angle plug heads
These small-block Chevy tight-fit headers are the most universal steel tube shorty headers available. They even fit difficult applications where space is limited. These block hugger headers are a favorite for street rods, as well as many 1950s and 1960s cars and vintage trucks.
