Nice uncracked pair of 68 442 Exhaust manifolds, X & Y big block 400/455 castings. The X is correct for 65-68, the Y manifold is 68 only. The only issues are the Y manifold needing one thread insert at the head pipe flange connection, and the X has the typical froze up (in open position) warm-up flapper. They have very little pitting at all, nice well preserved castings that would be show worthy after cleaning up. $225 shipped within lower 48 states.
