Help Identifying Valve Covers on MerCruiser 5.7

[eriefeelin]

This engine was rebuilt back in 95 by someone unknown to me as I bought the boat in 96. I've searched all over the web trying to find out the brand of these valve covers so I can get some new gaskets for them.
They have 4 center holes and seem to me made out of plastic/nylon compound. The gaskets fit inside a groove in the cover. These are on a 1990 260 Mercruiser Alpha One. Anyone familiar with these?

The heads havent changed so I`d say regular 5.7 gaskets will work
