[AJD] 35 D Runs Again!, but CRACK?

Thu Jul 15 16:37:56 PDT 2004

Also don't forget the lead washers, the D takes TWO per stud instead of the usual one. Since  you have a problem I would also spring for a new head gasket just so you can elminate that as a problem. Remember on these head gaskets, the smooth side (without the crimped edge of the fire ring around the bore hole) goes to the block. The crimped fire ring edge goes TO the head. I use CopperKote as a sealer to be safe on the head gasket.
Good luck
