These valve covers are on special because of discolorations and porosity.
The discolorations are on the sides.
The excessive porosity is on the corners. Porosity is small pinprick holes from tiny air bubbles in the casting process.
For reference, see our regular Chevy Small Block, Perimeter Mount, CORVETTE Script and Fins Valve Covers, Polish, PML Part Number 11026.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned. Please call to order.
