In the middle of putting a new manifold on my motor and cannot find the torque spec sheet in the manual. Luckily its a cold day and the Permatex will take some time to dry. If anyone can let me know that would be great.

Vette(s): 1969 COUPE CORTEZ SILVER, BRIGHT BLUE INTERIOR 383 cu. in. 512 HP. Hooker headers w/ side pipes PS PS AC AM FM STEREO. 68,000.MILES C5 5oth Anniversary Coupe , auto.350hp

I`ve installed a pair of Hooker super comp headers and side exhaust.

I have a leake where the tubes meet the collector. Leake on the top on the drivers side, and a leak on the bottom of the passenger side. There is only one bolt to tighten this joint,and i got it as tight as i can get it. Any suggestions?
