Yes Brad, the gasket you have pictured is for the B-1 heads and valve covers.

I can tell you this. OhioGTX, a close friend of mine has been using our #3186 with the Victor heads AND cast Mopar Performance valve covers for years with zero leak issues. If he had an issue I would most certainly be aware of it.

When I gave him the gaskets he asked, "what should i do for installation?" I said, "nothing, just put them on and tighten the fasteners."
To this day I believe those same gaskets are on the engine without issue.
