6.0 spark plug gaskets

[mjoekingz28]

When I replaced ac delco iridiums with ac delco iridiums from the parts store I noticed the old ones had a gasket and the new ones going in had no crush gasket.

 

 

Everything seems fine, but it seems like a pretty important part was left off.

rule of thumb was, flat seat, crush gasket....tapered, no gasket

I sincerely hope you used some "COPPER" Never seize on the threads and seat of the new plugs.
