Are there any heads for a Gen I motor (I think it's Gen I -1975 Chevy truck motor) that are close to Vortec heads, but with perimeter valve cover holes and the old intake manifold hole angle? I know I could switch to actual Vortec heads, but I've got the Edelbrock EFI setup for the Gen I heads and don't want to have to buy a whole new manifold.
The Dart Iron Eagles are somewhat similar. They also have a heart shaped chamber and can take early style intakes and valve covers. RHS sells a Vortec with dual intake bolt patterns but not perimeter valve covers.
