These valve covers are on special because of excessive porosity. Some porosity is normal but these have more than usual.
The porosity is mostly under the band on top and along the front edge.
There is some on the corners also. One corner has more than the other.
For reference, see our regular Chevy Small Block, 1959 to 1986, CADILLAC Script Valve Covers, PML Part Number 11107.
Be sure to go through our CHECKLIST before ordering.These valve covers do not come with PCV and Breather holes but can be machined for them. You must call to order the valve covers with machined holes.
This special should fit and function like a regular part.
This is sold as-is and cannot be returned. Please call to order.
