Best valve cover gaskets

[dustertogo]

Hey guys, what valve cover gaskets have you found that hold up the best to the heat from stock exhaust manifolds?
Thanks

Most any of them do. Feel-Pro is my fav.
90% of them not leaking is the Prep work. If the covers are not straight and crushed at the bolts they all leak.

At one time Fel-Pro had a part number for Police spec gaskets. Small block mid 80's.
Aspen,Diplomat,Grand Fury cop cars.
Bought some in the early 2000's. Maybe ?

Also, besides having a flat flange and not over-torquing, original sheet metal valve covers typically have football shaped, load spreading washers under the bolt heads.
