These valve covers are on special because the lip of the flange on the inside is very thin. In one place the lip is about 0.020 inches. Normally, the lip is 0.125 inches. One cover also has a discoloration on the front, below the CORVETTE script.
The lip of the flange helps keep the gasket in place during installation.
A custom PML set of gasket and new mounting bolts are included.
These covers can be machined for breather and PCV holes but you must call to order for this and there is a machining fee.
For reference, see our regular Chevy Small Block, 1987 to 1998, Center Bolt, CORVETTE� Script And Fins, Polish Finish, PML Part Number 11041.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned.
