Hi Gary, The local Chrysler dealer does not have that 1122893 part number in their system. I remember taking the heads off an old Chevy 409 (sorry! non-mopar!) and it seemed like the head bolts had some type of gasket sealer on the threads of the bolts. Could this have been used so the head bolts did not loosen up? OK, start with all those Cheby jokes now! It sounds like any head gasket sealer is not needed, but I thought I would ask first.

A lot of the old part numbers are still available or have been upgraded. Gary Hagy, Hamburg, PA In a message dated 1/28/2008 11:22:35 A.M.
