These valve covers are on sale because of excessive porosity.
Porosity is tiny, pinprick holes casued by mini air bubbles in the casting that show up when a part is polished. Some porosity is normal.
These covers have a lot, especially above the "BUICK" script and fins. It is also on the intake side and corners.
For reference, see our regular BUICK Nailhead V8 Fins and Script Valve Covers, PML Part Number 11080-2.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned. Please call to order.
