This head gasket was made for early 71-74 Z's with E-88 cylinder heads. It replaces catalog part #10-2441, which was originally for 70 and early 71 E-31 cylinder heads through 11/70.
Cylinder Head Gaskets should be matched to the cylinder block, not the cylinder head. This gasket should be used with E31 and P30 blocks.
