RHS Header Gaskets?

[71gtdart]

what header gaskets are you guys running on your RHS X heads? the gaskets I'm seeing are all smaller on the middle 2 ports than the ports of the head. Brian at IMM prepped these heads for me, but Im not sure if he opened the exhaust ports or if they come bigger than the stock X heads.

I just trim the gasket.
