The following from Toyota service advisory . VERBATIM:
"NEVER loosen the bolts before you torque them. This is not a good idea. This will cause damage to the head gasket which is already compressed and not in favor of recompressing (HKS headgaskets are, but stocks aren't). Besides that, it screws up the whole torque order, so you will put too much stress on the head as well!"
Scotch - Because one doesn't solve the world's problems over white wine.
