Good to see she's getting work done!!

A note about head bolts on 4g63b/4g64b/4g54b's, stock head bolts are reusable unlike the newer 7 bolt engines(crank bolt pattern) which use torque to yield style headbolts. I'd trust used Mitsu headbolts over cheap replacements, even felpro did not get it right and has slipped up with poor quality control. As long as your bolts are in spec and the threads are good, you'll be good to go.
