What's the best gasket to use with chrome valve covers on a 426 Hemi? Something that can be reused if removal of covers is necessary would be nice.

tsk Not in my experience. While I like the Superformance gaskets and use them, especially in places like the intake, they are just too hard to seal stamped steel valve covers.

Frankly, it is hard to beat the Fel-Pros. Less expensive, readily available and they work. I also use some valve cover clamps on the lower edge holes. https://www.amazon.com/Mr-Gasket-9899-Chrome-Valve/dp/B000BWAPRK

The cork felpros with the stainless wire sandwiched in the middle works great for me. I contact cement one side to the cover, leaving the other bare, and they can be taken off a hundred times without damage. Plus the thickness helps a bit for high rocker movement

I've had good luck with the Felpros with the metal insert as well. The metal keeps them from squirming.

I've never used these, but they look nice. I've used molded silicone on chevy stuff, and they worked great, and were pretty much indestructible.

May have to get a set of these and see, thanks.

iagree I've used those type of gaskets on the Camaro and reused them MANY times w/ no leaks. My hemi has the Indy cast covers, so all I need are the flat paper gaskets for it.
