Hello Davis, yes indeed, I have used the 72 dog leg heads on my 70 390 Block. Thanks for the tip on Midas but unfortunately the manifolds are on the engine and I'm not wanting to have to remove them at this point. Was kind of hoping someone on the forum already new the angles for the left and right exhaust manifolds? Have a good evening.

The angle should be the same as a 71 Javelin. Midas or any good local muffler shop should have a card with the angles on it. ?Good luck, ?Davis Today's Topics: ? 1. 1972 Free Flow Exhaust Manifolds (John Lunde) ---------------------------------------------------------------------- Message: 1 Date: Sun, 23 Sep 2012 22:14:54 +0000 From: John Lunde <lunde@xxxxxxxxxx> To: "amc-list@xxxxxxxxxxxxxxxxx" <amc-list@xxxxxxxxxxxxxxxxx> Subject: [AMC-list] 1972 Free Flow Exhaust Manifolds Message-ID: ??? <D90E41D5B51D2148AA42249A67015E5B656749FC@xxxxxxxxxxxxxxxxxxxxxx> Content-Type: text/plain; charset="us-ascii" Hello everyone, I'm trying to get a custom exhaust built for my 68 AMX for which I have changed out the stock manifolds to a set of later model 72 free flow exhaust manifolds. Can anyone help me out with the left and right side manifold angle for the downpipe of the exhaust pipe for the 72-74 Free Flow Exhaust Manifold? Any help would be appreciated.
