LS valve covers idea's/where to get

[Ron in SoCal]

Marty - I have heard some complaints in the past about leaky CF valve covers. Not sure whose brand tho. Looks like they come with an o-ring grove for sealing. Have you run these for any length of time? Also, what are the screws on the interior side (top right in the pic)...Katech mount holes?

Thx buddy!

Those covers do leak. They just don't seem to be able to stand the engine compartment heat from my experience. I had to swap a set out. They might be better now, but the set I had needed to be retorqued constantly. I think most automotive aftermarket carbon parts are not made with the best materials and do do well with ultra violet rays and engine temp. Real carbon parts cost big money and I'm not convinced the aftermarket will pay the money for top quality.

They are currently on the motor and have only run a few times. A local guy has them on his 9 Second firebird and hasn't had a problem with leaks to date. I am hoping I get just as lucky because I really like how they look.

Those hold the aluminum brackets to the interior side of the valve covers.

ps - Very few aftermarket valve covers will ever work as good as a factory valve cover no matter who is making them as most suppliers don't have the money to match the OE quality.
