I use the O.E.M. silicone coated steel gaskets from a later model F.I. engine. They require FLAT valve cover rails and covers.

The Cometic are as tough as I have seen.

Cometic are the best I’ve ever used! Probably been off 50-75 times and still no problems. They’re a little hard and don’t like swapping around or they’ll leak till seated back in.

I've had pretty good luck with the Cork Rubber Fel-Pro's FWIW!!

I've had good luck with the blue silicone, steel cored ones from Moroso. Take them off often to check lash and no leaks
