1983 Other Chevrolet Models

I am rebuilding a motorhome. It is between a 1970 and a 1985 chevy small block engine. 350 cu. inch.
It is a 4 bolt crank (heavy duty).
I need to know the head bolt torque number, and the intake manifold torque and exhaust manifold numbers.
It is a 400 automatic transmission. I need to know the flywheel to converter bolt torque also. Is there
a place on line where these are posted?
thanks,
Shirley

head bolt torque is 65# start from centner and work your way out on each end. Intake manifold is 25# same sequence. Exaust manifold is 25# start at center work you way to ends. Torque converter is 55# And yes you can try the library and any 350 from any early year trucks will have the same torque numbers. It didn't change until the later 90"s
