Big Block Mopar Stainless Header Flange for Indy 440 Raised Port Heads

These header flanges are specifically made for RAISED PORT Indy Cylinder Heads 440-1 & 440-SR Cylinder heads. These flanges will NOT work on older OEM iron heads, as they are too tall and will interfere with the valve cover mounting points.
