Need help with valve covers leaking

[12many]

they are greyish colour, steel with silicone rubber ribbed, they seal! also you cant over crush them with the steel in there. If the cover is flat your good to go.

Sounds like worth $60 to me, considering once they are on I won't have to deal with leaks which means not pulling the seats and the side covers of my doghouse to mess with, hopefully!
