Never take it back to Donald B Rice Tire....Only the left rotor was replaced???

Head gasket was replaced at 89k and 145k....Seems a little much...Either A) They used cheap head gaskets, or B) You may want to look into the cooling system. 55k between head gasket changes is far too quick for my liking.

There has been a lot of $$$ invested in that car. I tell you that. That is easily over $10k worth of work. It looks very nice.

Rough idle is not your timing chain. If it was your timing chain things would be a lot worse than a rough idle. Start by reading through CIS-E and understand the system.
