head bolt idea

why helicoil? didn't see anything about stripped threads???

Anyway I'd say don't do anything if it's not blown. (and certainly DON'T take the bolts out one at a time or in any other order than by the book!!!) Just wait till the first signs of it going (and it will eventually) and then follow the tsrm replacement guide but either use upgraded bolts/studs following their torquing instructions, or use new stock bolts (which are fine) just following the upgraded torque level & not the original 58lb rubbish

And when done, remember to burp the cooling system unless you enjoyed it so much you wanna do it all over again next week...
