Ive looked around for the torque specs for an exhaust manifold on a b18c1 motor. Im talkin about the 7 header to head bolts and the 2 outside nuts. the torque specs for the outside 2 nuts is 23ft-lb. For the header to head bolts is said to be 22ft-lb. when I got here they all felt somewhat loose. Whats a "realistic spec" to follow. I know 23 on the header to head bolts was not enough to I went to 30. any thoughts? its fine with no leaks. should i leave it or back it up. I also had an extension on the wrench. does this matter?

there DC's case that makes a difference
