I got some NGK iridium plugs but I want to know if I need to change the head gasket to at the same time?

 

Why are you pulling the head to change spark plugs?

Here's a write up w/pictures on changing plugs. It's for a turbo, but you it'll give you the general idea.

I mean the gasket between the heads and the cover I have to remove to get to te plugs. Whats that gasket called?

 

The plugs are under the coil packs under the plastic beauty cover. There are no gaskets involved in replacing the spark plugs that I know of. It's always recommended to use dielectric grease on the part of the coil pack that fits over the plug to keep it from sticking. Also use anti-seize compound on the spark plug threads to keep from galling the threads on the aluminum head.

 

I was told that there was a gasket between the. Beauty cover and cylinder heads that needed to be replaced.

 

Good luck.
