This is Exhausting

OK, thank you all for your advice, I got the drive side exhaust manifold mounted using the anti seize compound and torquing the bolts to 24 ft lbs as recommended by the Haynes manual, then I saw this post on another forum:
"... Also a big warning!!!!!!!! The use of any lube other than light oil will alter the torque needed to tighten the bolt/nut. The rule of thumb is to lower the torque setting by up to 30%. The anti seize reduces the friction between the threads so if you think you want 100# torque and go that tight you will be grossly over tightening the fastener and may even break it. "

I have never used a gasket on a iron manifold to a iron head either. Never had a problem. When I did use a gasket I just had a place for it to burn out. Just check the manifold with a flat file to remove any burrs. Use anti seize and torque.
Well I got the second exhaust manifold back on today. I tapped the holes, scraped the old gasket off, applied some anti seize and torqued the bolts.
