homer41 Posted November 21, 2019 Report Posted November 21, 2019 I am installing int/ext manifolds on my 218 plymouth stock manifolds. I bought a manifold stud hardware kit. I think I have it figured out but want confirmation. My guess is that on the exhaust manifold outer ends it takes 2 steel locknuts and 2 brass washers on each end. Then the 4 steel washers go on the studs that secure both intake and exhaust flanges and all of these plus the remaining studs get the brass nuts. Can anyone confirm or correct this for me?

Doug&Deb Posted November 21, 2019 Report Posted November 21, 2019 I believe that’s correct. Remember to finger tighten the intake and exhaust together only until you’ve tightened them to the block. Otherwise you’ll almost certainly crack one or the other. Quote
PT81Jan Posted November 21, 2019 Report Posted November 21, 2019 (edited) My kit included an instruction. Posted that some time ago -> https://p15-d24.com/topic/46957-brass-manifold-nuts-and-washers/?tab=comments#comment-498478 Hope this helps. Jan Edited November 22, 2019 by PT81Jan 1 Quote
homer41 Posted November 21, 2019 Author Report Posted November 21, 2019 Thanks Jan! I would not have guessed that the conical steel nuts were supposed to go into the conical washers, I just thought they were regular lock nuts, now I have to look at the washers more closely. Dave Quote
