Description
AFR SB Chevy Eliminator Spread Port Racing Heads have the center exhaust ports spread apart 5/8″ over stock L98 GM heads. The reason for spread port heads is to achieve additional cooling in the center of the head where the heat concentration is greatest. As standard headers do not fit, spread port headers are required since the center ports are spread further apart then stock GM products. The increased spacing on the exhaust port also requires the use of exhaust gasket Fel-Pro 1409. Spread port heads only come with a Stahl bolt pattern. AFR’s spread port head has all the benefits and features of AFR’s standard head.
