For heavy breathing, Brul chose these AFR 325 as-cast lungs with blended chambers for our monster build. They feature a 0.750-inch-thick head deck and reinforced rocker stud bosses. These brutes flow an amazing 385 cfm on the intake and 285 cfm on the exhaust, all at 0.700 inch of lift. View Related Article
