Can anyone tell me the correct torque for the head bolts on a model T? Prestone seeped out of the head but I found the head had not warped an d just need to replace the head gasket.

I believe most of us use 50 foot pounds.

There are no torque specs for any bolt on a Model T, just tighten till tight.

For head bolts it would depend on the grade of bold used. I used grade 5 head bolts and torqued to about 35 Ft-Lb, worked great. Of you know what modern grade of bolt used, there are charts that show the recommended torque.

I think the "red" engine book say torque to "about 55 lbs" I use 55 and it works for me. It would also depend on the condition of the threads in the block . I always take a bright light and after I chase the threads and blow them out I look closely at each holes threads to see how they look. I then screw a bolt about 1/2 way in and " wiggle" it, to much "wiggle" means the threads are worn so I would use less torque in that case.

I use the Ford wrench. If a torque wrench, 45 to 50.

Don't forget to retorque after a few heat cycles. Also, do use some of the purpose made copper head gasket spray on the head gasket first.
