Which Remflex gaskets?

[SSG_Karg]

I need to replace my header gaskets and planning to use Remflex based on the high reviews on them. Looks like they offer 4 or 5 different sets for SBM. My application is J-heads and 1.625” Hedman headers. Anyone know which ones will fit best?

That mostly depends on your exhaust port shape.
Stockish dodge small block heads have an odd shaped port on the center four cylinders that the square port gaskets tend to get off the edge a little into the center headbolt cutout, so I think you need the Part Number: RFL-6004 but check it out.

The header flange is semi square and the port isn't but they still seal great.
