Cannot understand why radiator end of heads has a valve cover gasket platform likely twice as wide as is firewall end. Would Edelbrock does this deliberately,,,would seem odd as the rear of the head is where the majority of pooling is likely.
Heads are bisexual.
I have Indy covers (no logo) on a set of Edelbrock Performer RPM heads. The only gasket they didn't like was the blue, rubber, Moroso one with the steel shim. I tighten them "palming" a 1/4" drive ratchet moving inside out like a head or an intake. I go until they stop turning going over all the nuts about three times. Studs are the way to go if you have room to lift them off the extra inch or so. Prepare to grind some aluminum off at the distributor.
