So are you going to put new heads on it and keep stock turbo at stock boost and stock fueling? If so, new head bolts are ok. If you are trying to make an improvement then head studs. Don’t make the huge mistake of finding cheapest heads or you will get practice again very soon at removing those cheap heads. If your broke then rework your heads. Otherwise optimizer heads or p400.
Are you 100% the rest of the engine is good? Imo it is better to rip the engine out and all apart to fix everything at once instead of just doing the heads if you can. A common thing I here when helping people on these engines is 1 year after they started the repairs “Dang I wish I planned out the whole engine from the beginning.”
If you cant afford it all right now, plan it out and build it in stages.
Learn about the head stud leak and fix options before buying. Head studs are NOT the right answer for everyone. You are trading one risk for another.
Are you happy with the stock power and mpg?
Any issues getting hot you want to address better while apart? 220 is overheating to the point of pull over, 210 you better watch the temp gauge as much as the road. Ignore the nonsense you hear from the company wanting to sell you new engines or new trucks. Military says 240, but they cant get 50,000 miles from and engine.
Take the time to learn all the issues and how you are going to address them before you start or you will have the regrets others learned the hard way.
