Just when did Ford start using these head bolts? I see what I think all too many tending to re-use the head bolts. From what I understand, the later stock bolts are a one time use item, streched to the limit at initial installation.
Im not sure when they started using them. But from what Ive read you should not re use any bolt used for the heads, rods, main caps, etc.. unless they are a aircraft quality type like arp.
Even then depending on mileage I would replace them also. But thats just me... personal prefences for me is if I change anything ill put in new bolts... and depending on what the part is ill use aircraft quality bolts... things like water pump Ill just go to home depot or lowes... Ive had better luck with there 8 grade zinc coated bolts (gold looking ones) corrosion wise then arp black coated stuff... on exterior parts.
I tell everyone I can to toss the torque to yield bolts in the woods. I use ARP for everything I can, odd thing is should you need bolts, the ARP's are cheaper than the stock wimpy bolts.
