You either need the exact part number from Ford or the specifications of them so you can source them from a fastener supply company.....if you want to do it right.

You have about a zero % chance of anything going wrong if you simply get replacements (for all of them) with a grade rating of 12.9 (ratings are different from standard to metric fasteners). And probably a new torque wrench.;)

I'm pretty anal about that kind of stuff when it comes to engine building (I go as far as to replace all bearings with ceramic ones, which is rather silly) and I would have no issues with replacing all the cam cap bolts with 12.9 grade fasteners, chasing the threads with a tap and lubing the threads up before tourqing.

And when it comes to Torque wrenches you get what you pay for unfortunately. after snapping a few things with Crapsman torque wrenches I got a set (1/2, 3/8, 1/4 drive) Snap On wrenches and have never had a problem since. They cost somewhere about a billio $$ though.:happyhapp

Right out of my service manual Camshaft bearing cap bolts N807834. Torque is 89 in/lb. Just in case you were not aware the cam phasor retaining bolt is a TTL (Torque To Yield) bolt and MUST be replaced. It's not a matter of if it will fail its when it fails if you try an re-use it.
