torque spec

i have a '77 chevy 350 V8 and wanted to know if anyone knows the torque spec for the exhaust manifold to block. the chilton's book i have doesn't have it for my V8, but the I6 spec says 25 ft/lbs. Can i use this for my V8?

Yes. 3/8NC bolt, at least grade 5, 25ftlbs is a good number to use
