Guys I’m rebuilding my first 351 that is out of our ‘93 OBS F150. Heads going back on this weekend and all along I was thinking I could reuse the head bolts after a good cleaning, BUT some where in this time frame Ford started using Torque-to-yield bolts. How do I know for sure which type bolts these are?

I did browse around the forum first, but actually read conflicting info in several threads.

These bolts do not have threads all the way and they do have heads w/ integrated washer (non moveable).

thanks in advance for any guidance, Clay

 

You're good to go. Those are standard. My '95, 351, same way. No TTY.

 

Okay, thanks for the quick reply and conformation on this. Didn’t want a bolt to break off after all my hard work.
