I'm not too far away from putting the heads back on my 35 engine and have
the correct torquing sequence but need to know the final number I need to
torque them to.

Never more than 50 ft. lbs. no matter which heads.

Also remember to re-torque them after several heat cycles. Actually several re-torque checks are a good practice.

Do you have to loosen before retorquing?..... Mark
I read somewhere about “slip tighten”?....you dont get an accurate reading by just tightening.

I was taught to back off 1/8th turn and retighten through the torque chart 1 at a time. Have never had any problems with head gaskets. I always do at least 3 Hot/cold/re-torque cycles before there isn't any more movement.

I often wondered about backing off the nuts and re-torqueing. Would this not have the potential to also move the stud causing a leak on a fresh engine?
Just a thought..
