Replace head bolts?

If you can't find bone stock head bolts use the best you can. Your car I don't believe is BONE stock anyway. None of them are out there. And further more

If you really want to use original head bolts then I recomend that you get a set of head bolt washers used for racing. Then scrounge the salvage yards for a old V8 SB or BB motor that is out of a original low mileage 4 door car and get the entire set. If you inspect them close you can tell if they look like they have been used before by the flat sides of the heads of the bolts. The are metal and will not wear out without help or over tightening.

Clean Clean Clean. both the block holes and the used head bolts. Be sure to use a thread sealant and start to tighten them using a good tork wrench and start at 20 lbs under final value and keep working in a circle starting at the center head bolts and work out increasing it by 10 lbs at least two times. If any bolts don't feel the same as the others stop. Pitch it and start that side completely over.

You can reuse GM head bolts many times if you don't over tork them past their recomended value for your motor. The most important thing is to use good head gaskets. If you insist on using OEM GM steel ones I had good luck and never blew one when I put them on I would hang them on a hook and spray them with silver krylon and slap them on the block while they were still wet. The last and most important thing is to re-tork them one last time while the motor is hot after you get it running.

I have done this too many times over the years and never had a problem. Be sure to use a quality 6 point socket from a tool truck and not just any orential junk. If it don't have a known name brand on the tools you use, you may be sorry.
