[TR] ARP Head Bolts

[bill_beecher at flash.net]

After violently breaking a head bolt last fall I decided to order a set of
the ARP bolts and change them out this winter.  So now I have them and I see
they come with this odd little 12-point nut, so I have a question for those
in the know.  

I don't really like the looks of these new nuts as my car is 99.9% original
so I am wondering if there is any serious issues with re-using the old nuts
on the five studs that are visible from outside the engine?
 
BTW, I always torqued in two stages to 105lbs, but ARP says three stages and
110lbs.  Would 50-80-105/110 be about right?  
 
TIA,
Bill
