    I am using '67 era 273 exhaust manifolds on my '94 Magnum. I used Magnum gaskets and they lasted about a year before blowing out. I know that there is a port mismatch between Magnum heads and LA manifolds.

    My question- What gaskets should I use? Magnum or LA or something for headers? I am planning on using Remflex gaskets.

    Remflex Exhaust Header Gasket Sets 6004 Magnum gaskets
    Remflex Exhaust Header Gasket Sets 6027 Pre-Magnum
    Remflex Exhaust Header Gasket Sets 6003 Headers
    Remflex Exhaust Header Gasket Sets 6016 LA with 5-bolt valve covers

    Thanks.

    I normally don’t run any gasket. Have the manifolds resurfaced and use a thin dab of ultra copper around the ports if needed.
