Basically i did a head swap on a 98 lincoln towncar the spark plug blew out and destroyed the threads for the second time.I put another head on from a 99 everything is back together it runs but runs rough.I did a compression test the driver side all 180psi the passenger side the head i replaced where all 120.I have a running lean code on bank 1(pass side) i torqued all the bolts down to spec the timing is right also.I was thinking maybe torque the head bolts some more i did use a cheap ass torque wrench there are no other leaks what so ever.Any ideas?
