Anways, my intention was installing it in the splash well area. Since it's exposed, I decided to go with the aluminum head for durability. I may still install it in the bilge. I just need to verify if I can get access for the gas line down in there somewhere.

The X is where the nipple is for the gas line in my splash well.
Anyways, so the kit showed up today. I was looking it over and notice this.

The dark spots on the ring is pitting. There's 1 very large pitting. And several small ones. You can easily make out 3 in the picture. Anyways, this is the surface where the rubber seal will meet.
Is it a problem? Or can I just use it as is? Only hassle is, I bought it online.
