Jean-Yves, casting # 2268253 is correct for the right side exhaust manifold on a 300H with the 2-4bbl's. The left side casting # is 2205536 and was used on all 1962 Chryslers with the 413 engine. I don't know what your other # 1739600 is for. Doug Warrener -------------- Original message -------------- From: "jean-yves chouinard" <jymopar@xxxxxxxxxxxxxxx> Hi all. I have a set of exhaust manifolds ; castings are 1739600 and the other 2268253. Anyone knows if those are correct for a 1962 413? One of those(passenger) has a hole on the top I think it's for heating up the choke for a 2-4 bbl set up maybe?? Thanks! Jean-Yves (K-Conv. etc... in cold cold New Brunswick right now).
