bought the LS6 front coolant pipe and 2 block off plugs. it looks like that the new plugs and crossover pipe come with a rubber O-ring already there to seal the tubes off. do i need to reuse the stock coolant pipe gaskets for these or should the o-rings be enough? use both? thanks

I think the o-rings replace the gaskets. Someone can chime in to confirm this.

the oring appears that it should be thicker to form a better seal

up for a confirmation before the night ends.
