Tigthening torques, 47 intake manifold/exhaust manifold bolts to cylinder heads

[FinCad]

Hi

I am lacking the repair manual for my 47 convertible.
What are the correct tigthening values from intake to cylinder heads + from exhaust manifold to cylinder heads ?

Thanks in Advance

Sami, The torque for those bolts including the crossover should be between 25 & 30 ft#. Be sure and start in the center and work your way back and forth to the outside. I think it is a good idea to start at 20#s and go in 5# increments and then go back and check them all. It is also a good idea to re-torque after running the engine up to tempurture the first time along with the head bolts.  Good Luck,    Harry
