this seems like an obvious question if I understood the limitations of torque-to-yield bolts... but I don't.
Frank has hopefully saved me some misery by pointing out that 72 ft lbs (from orig. shop manual) is not enough torque for my head bolts. My question is this:


Is it okay to just do another 8 lbs of torque (to 80 ft lb) in the correct tightening sequence on the bolts I have now?


Or, once they've been "stretched" do I run the risk of popping them? Should I just install a new bolt set? Cost is no biggie, but I wondered if doing that runs the risk of oil/crud falling into the bolt hole -- requiring another cleanout, more work etc. By the weekend, I will most likely only have about 100 miles on the vehicle since buttoning it up if this info makes any difference?


Another request is anyone's opinion on the bolts themselves:


I went with Mitsubishi head gaskets to avoid any problems, but picked up a set of Fel-Pro bolts thinking a bolt was a bolt. Any opinions on this? Should I replace with Mitsu parts as long as I'm tearing into the engine??


As always, thanks for the info and advice!
