Headers hitting idler arm

Hey all,

I installed TTI headers on my car a while back on my '74 Barracuda, and not long ago when I was rebuilding the front end, noticed a divot in the header just above the idler arm. Looking at the divot, it's clear that the idler arm caused it from being far too close. My experience with the fitment of TTI headers has been great in the past, so I'm thinking it's an issue with the suspension sagging, or I need a spacer between the engine mounts and K frame. New shocks, new engine mounts. The divot was there before rebuilding and the spacing is still very tight after the rebuild. I've also noticed that the oil pan sits pretty close to the center link. 318 car that now has a 440.....does the 440 sit lower?

I added spacers on my Scamp a while back to help with clearance with great results, so I'm thinking that might be the route I go. I'm wondering if anyone has had this issue with their E body? I'll post some pics shortly.
Pretty much, just get some really big thick washers and slot them. You can loosen the nuts and just pry bar the motor at the mount 'up' and slip them in.
