leaking...f...king valve covers ???

We had problems getting a set of cast aluminum valve covers to seal on a 440, trying 7 gaskets and still not sealed.

Pitched the valve covers for a set of stamped steel chrome ones and they sealed first time...

Because stamped steel flexes and cast doesn't.
Straight inflexible edged covers don't like non straight inflexible head rails, but some creative gasket making works.
This the same reason some report success using double gaskets.
