Manufactured exclusively for BP from the original Fitzgerald dies used for GM in the 1960's and 1970's. These head gaskets will crush to approximately .045.

Also has chambers for the 326-389-421 (and Early 1967 400)

If the block has the offset type/location of valve notch then it requires this 19375 gasket. This 19375 gasket also works on a block with the later style valve notches (@ 3:00 and 9:00 locations) OR on a block with no valve notches. It is universal.

Recommended installation: Spray the metal side lightly with copper coat and let dry about 5 minutes, spray lightly again and let dry. The metal side goes to the block & the composition side goes toward the head. Do not spray the composition side.
