Actually aircraft grade bolts are around grade 3 if the remember is working 

Justin  if you read carefully ---- it was not standard A-N hardware that was mentioned.

It was "High Strength"    like Cat but better.      Cat is fine as far as I am concerned.
But Cat only sells a small amount of bolts compared to the aircraft industry.

Look up in a catalogue for high tensile bolts and studs. I would use a stud.
That way you can use every thread in the block. They cost a lot of money so the best
way is like Gary Bangs said   Raceway studs.     Bangs on.

Exactly how critical are the headbolts ?  very.   I know of bolts letting go on Cummins and GM's
and what not.Long time after they were installed. Go for quality.    IF need be do a brinell test.
and a magnaflux.        Why fuzz so much ?   ---  head-gasket leaks ---that's what.

A fuzz in time saves nine.   I am fuzzy believe you me. ---kind of let you sleep at night without night mares.    ----- If you did NOT fuzz and something let go ?   ah --got it ?.

If the sprocket on cam slipped ?   and bolt was not fuzzed ?   ask Shalyn.

Hagar.

PS:  My cam bolts are 45 foot pounds. And I sleep at night.
