what were the symptoms of the engine when it broke down?
you may be lucky and just get a new head gasket, head bolts, and get the head machined and the block cleaned and you can put her right back together
don't forget to torque the head down to 72ft lbs not 58 like the manual... unless you wanna do another hg
and there's plenty of 7mges/7mgtes around, look in local junkyards or buy from an engine importer
