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.
