Forth Time's a Charm

When does it end?  New head bolts, new gaskets...  I just have never been able to get this thing to seal.  I've tried numerous torque wrenches, oiled the stretch bolts, and tried black magic.  Nothing works.  I've run out of things to blame.  Everything keeps pointing back to these aftermarket gaskets that I've been getting from the UK.

Finally, a stroke of luck.  I turned up a a genuine Perkins branded head gasket here in the USA at TAD.  Please, sweet little baby Jesus.  Let this work.  Fourth time's a charm.  Right?
