Good and tight should be fine. I reused my stock gaskets and stock hardware, nothing else. No leaks.
Are those the 1 3/4 or 1 7/8?
+1 just make them as tight as you feel them right. i read that they should deb around 20 ft lbs. but you won't be able to stick a torque wrench in some places so i just made them as tight as i seem fit.
