COMETICGasket C5818-030 MLS Exhaust Gasket for GM LS1 - Pack of 2

Good gasket, however the rivets that hold the Layers together must be in correct orientation as they are not markedAll rivets do not clear spark plugs I recommend marking the orientation with a sharpie once confirmed (Driver/up/ Out ~ Passenger/up/outI fought to install the headers (2 hours) only to realize the rivets attachment point wouldn’t let the spark plug boot go in. I recommend this product if I knew them what I knew now.We all live and learn 😂

These are just about as good as oem you always want to go with a MLS gasket every time these are good ones.
