How do I replace my valve cover gaskets?

[PeteB]

What engine?
On later model LT1 engines (like mine) they used a composite valve cover with 4 hold down bolts thru the center of the cover.
The gasket is nothing more than a rubber o-ring material that you just replace by taking out the old and pressing the new one in the groove.
The earlier LT1 engines had the same 4 bolts, but were made of metal. Altho I never worked on one, I assume they also used an o-ring because of the similarity.
If you have an LT5, or an L98, you will have to wait for other responses.
