I'd think twice about having any local mechanic do this level of work
on your car. These I6 motors are far more complex than an average motor;
the head needs to be glued together prior to getting reinstalled and these
procedures are beyond most shops.

I'd try to source a factory rebuilt long block with a 2 year warranty
rather than chance a local place that may offer a warranty but may lack
the resources to really make good on a job more complex than they realized.
