Different head gaskets
I have a question about Head Gaskets I am installing a set of 243 heads I had CNC ported with over sized valves from Texas Speed. I ordered the head gaskets and bolts with the heads. The head gaskets they sent me are a layered metal type and are from GM part #12498544 I have seen pictures of some other LS1 head gaskets that seem to be a regular fiber type on the earlier ones. I was just wondering if it OK to run the new head gaskets. My car is a 2000. I am thinking that they just upgraded the head gaskets in the later years but I want to make sure before I bolt them on tomorrow. Thanks for any help you can give me.

And if you ever have to pull the heads again, the MLS gaskets leave much less to clean than the fiber gaskets.
