wrong head bolts
So I am replacing the two rockers and bridges on my truck. Was going to remove one head bolt and re torque the new one then do the next one. Went to put in the new head bolt and it would not torque down. Low and behold it's not the right size. It's to small. Funny thing is I got the bolts from my local ford dealer. How is it possible that they sell me the wrong head bolts. Are there two different sizes? Or has my block beem drilled and re threaded for some crazy reason?.Mine look to be about 8 and 1/4 inch long and about 1/2 inch or 13 mm in diameter.

I think you are right in that they gave you the
wrong bolt for the location you putting it in.
I also think that if they don't make you pup Happy
with a bone to chew on that one of there legs will
work as well.
It would be nice if someone would post a photo of the
bolt set for the heads. The TTY and the reusable ones
side by side.

Little note on things.
I just looked at the ARP bolt kits. They tell the size but not how long they are.
The main bolts are 14mm

and the top inner row are 8mm

Is there a way to tell if I have the non tty head bolts. It would be great to re use these bolts since nobody in my town can seem to get me the head bolts I need. I am tempted to run with re using the bolts I removed and check them for torque in about 2 or 3 weeks. Any thoughts. Maybe by then I can locate two new ones. I need my truck back on the road I have been borrowing my friends car and he needs it back

You should go back and read the link I posted about TTY bolts.
They are permanently changed unlike normal bolts that stretch and
relax back. If you reuse them you run a very high risk of one snapping
down in the engine. You don't want that to happen. If it did the cab might
have to come off to get enough room to lift the head from the broken bolt.

Anthony,
He looks to be somewhere in California.
Do you happen to have a photo of the top bolts?
I was unable to find any thing with the length for
then listed on it.
Hope you had a good Thanksgiving.
