Does anybody happen to know the exhaust flange torque to cylinder head off the top of your head? I think it's 110 inch lbs. but I'm not sure Thanks in advance.

Thanks for the response. Looking at the SB I think we have the .31-24 studs but I'm not sure and my airplane is an hour away so I can't check it out today. The .31-24 spec. is 200-210 but that seems a bit high to me. Let me know what you think.

You are right about that! Nothing worse than the feeling of a stud snapping. Been there done that. I bet the exhaust falling off cought your attention though. 8O
