Felp-Performance #1612 gasket and the Fel-Pro VS50145R?... exact same gasket.. different packaging. These hi-temp gaskets are rubber-coated fiber and designed for extreme hi-temp OE applications where the cast iron manifolds rise up and very close to the valve covers... intended for ... and tested on emergency/police/fire/ambulances, city taxi-cabs, trucks, heavy-duty industrial vehicles, etc. These are best hi-temp gaskets on the market... period... and intended for longevity. Just remember.. flatness and proper clamp load! They are not as compressible or forgiving to distortion as cork-rubber... also available for Mopar small-block LA covers.
