Hi all and a Happy New Year to you. I was having some issues a while back and you guys are great, lots of help and very much appreciated. This is my first T, a 26 coupe. Really nice car, excellent body but doesn't run for crap.
Anyway, long story short, I put in a new head gasket and new head bolts but I have no idea what the torque should be. I currently have them at 60pounds of torque. Is that enough?
60 is plenty, generally 50 or 55 is used.
Thanks Andy, have a great new year.
I have stripped threads out of a block using 60 lbs. Since then I use 50 and haven't had any problems, with either stripped threads or leaking gaskets.
I used 35 ft-lbs on mine, worked well.
That's the lowest I've ever heard. 50/55 is what I use and of course a re-torque after heating it up to operating temp and an overnight cool down. the dope is to do it again after 500 miles. Never have.
What are you guys using for head gasket sealer?
If you really got them to 60ft lbs without ruining anything, you're lucky. Ford did not use torque wrenches on any bolt installed in the factory. In fact, paragraph 373 of the service manual only instructs to tighten the head bolts evenly.
I install head gaskets dry and a final torque of 55 ft/lbs. Never had a problem which doesn't say I won't strip a thread on the next one.
Uncle Jack -- I use Copper-Coat in the little can with a brush, not the spray kind. I smear it generously on both sides of the gasket. Nothing against the spray, I've just never used it. Maybe I'd like it better.
I use the Copper Coat spray version. No issues that I know of. (knock on wood)
I use Copper-Coat spray. It is quick and easy to get a nice uniform coating on both sided of the gasket.
50 lbs. torque. Copper spray gasket sealer on all four surfaces gives the most uniform application. Re-torque again to 50 lbs. after running up to full operating temperature and cooldown. Jim Patrick

Correction. I sprayed it on both sides of the gasket, but not on the block or head surfaces so as not to spray it on the combustion surfaces, cylinder heads, walls or valves. Jim Patrick
I like the copper spray, too.
The benefit I see about using the K&W brand that Jim posted for my Model T is that it, "Won't harm oxygen sensors." However, it does NOT say anything about not hurting distributors or water pumps...

Is the 50-55 pounds appropriate for a
Aluminum Z head?
This may help Wilbur, less pounds for Aluminum.
'Z' Head install instructions packaged with the alum hi compression head.
"What are you guys using for head gasket sealer?"
1 or 2 coats of aluminum spray paint on the gasket, works good and easy to clean off if ever removed.
1915 touring. Copper coat and 35 ft/lbs (in 5 lb increments). No leaks.
Stock engine; Grease or copper coat or both depending on the condition of the used head gasket I have on hand. Knock on wood, has held up so far. Your experience may very.
