Head bolts
A lot of discussion about torque settings for head bolts and breaking same at 55 pounds. No one ever mentions stripping the threads in the block at 55 pounds.I assembled my engine after a valve grind and the last bolt disaster. Stripped the threads a t about 45 pounds. Had to tear the whole job back down. Helicoil did the trick. How many people have stripped the block threads ????? , Now I hate the thought of having to remove the head if the it has to come off.

Re: Head bolts
WELCOME to the Land of Old Fords!
Are you talking BOLTS OR STUDS? If it is bolts, they are not original to the engine and if so, may be someone installed bolts with not enough thread engagement? This stuff is more then 3/4 of a Century old and we do not know where it has been and who has been working on it. Usually, if you have had an engine apart and the studs out and got everything back together and torqued up, the next time you work on it, you should not have a problem BUT there are no guarantees. This is not a good thing when it happens but it does. Actually, removing the head to install a heli coil is not too bad. I like to install new hardened studs that usually have better engagement in the block. Lets hope you do not have this problem again. Chris Last edited by CWPASADENA; 07-03-2010 at 10:14 PM.

Re: Head bolts
Not to be a horses xxx. I grew up in the motor city. Ran a Medium Maintence Company attached to the 9th division in WW2. Never did we stud down a head. We always bolted down the head. So why so pickney unie about head bolts. Almost anyone connected to automobiles knows head studs are used to stud down a head. Now thats that. Tony
