    These valve covers are on special because of excessive porosity, especially on the intake manifold side, near the PCV and breather holes.

    Porosity are small pinprick holes that occur when polishing a sand cast aluminum part. Some porosity is normal but this part has more than usual.

    The excessive porosity may not be visible once valve covers are installed.

    For reference, see our regular Chevy Big Block, 396, 427, 454, 502, CORVETTE Script, Tall Valve Covers, PML Part Number 11042.

    This special should fit and function like a regular part.

    This is sold as-is and cannot be returned.
