From my experiences I would have to say no. I have had blown head gaskets due to stretched head bolts with SBF's & my 557. For no more money than a set of ARP head bolts cost, it just makes sense to switch. If you can use studs then that is definitely the way to go. I haven't had a problem since. Just my opinion from learning the hard way. Good luck.
Call me anal, but I toss all the OEM bolts. I use ARP, and I prefer studs to bolts. And on about my 5th reuse of an ARP bolt, I think about tossing them. Sure - if you use studs you might have a problem pulling a head with the motor in the car. However, the way I look at it is if the thing is so screwed up that I feel the need to pull a head, I'll just yank the motor.
If they are pitted by rust or damaged, I would replace them. If they look new and have been kept well oiled, I would use them. I never bought any new bolts or studs on my 466 with 14:1. Just 145 ft-lb in several steps in the correct sequence. I even re-used the Fel-Pro head gaskets over and over. On my 641", 16.5:1, Yes, I use studs, but I will re-use my head gaskets.
Mild 466 with 10:1? Sure, you can reuse your old headbolts. Ford 460's came from the factory with more compression than that.
I know plenty of people running their 466's/oem head bolts with more compression that your motor, and they run the engine at a sustained 5500 rpm all day long, and they have block cooling system pressures that exceed 25 psi, sometimes more. No problems.
Chances are that if you can't get the Grade 8 135 foot-pound clamping force oem headbolts to work in an NA application, the problem/culprit is more than likely elsewhere.
This is my third tare down (same bolts) i'm re-using mine! 14.5 comp, head gasket's look good. as long as the head add block are flat and the threads are good and clean. so you get the proper torque I see no problem. good luck. Ed. :wink:
