Hey guys My last rep[ly was for normal head gaskets. The best thing i have found
to seal copper head gaskets for is holden stud sealant :) I had leakage
problems at first too best thing to do is get new head bolts use the old ones
temp and tighten them 10-15nm more than standard torque this will help the
O-ring cut into the gasket leave like this for a day or so getting it warm a few
times. then using the new head bolts Replace one at a time tourquing to
standard spec. Head bolts are relativly cheap and I got some azure one at around
$30 a set.
Cheers Andrew
