So final solution: going with what I should have done from the start and getting TTI full tube headers. Everyone knows they're the best (for performance AND fit), they're just pretty expensive. About $250 more than the Doug's. I really wanted to go with the shortys even though the idea of losing 15-20ft/lb of bottom end torque really wasn't sitting well with me but they're not in stock and would take 6-8 weeks before they'd ship. Not gonna happen, so I cancelled my order. At first I was going to try and make the magnum manifolds I have work but they're both rear exit truck manifolds and would take some serious tube bending magic to make it work on the passenger side. Then I decided to just buy some reproduction manifolds for a 340/360 and throw them on. No dice, nobody makes em. Then I figured I'd just get some cheaper shorty headers but they're all center dump on the driver's side and would also take a miracle to fit right. THEN I figured I'd buy original manifolds off eBay but I was looking at spending close to $500 for a decent set, not counting shipping. So here we are.
The good news is that I can just pack my old headers in the box for the new ones and recoup most of my costs. I didn't ding them too much and the coating is still in good condition since I did the break-in with those manifolds so it should sell just fine. I should get the new ones in 5-6 days. That's cutting kinda close to the car show but I should have plenty of time to get it all together since I'll have kid-free evenings and weekends until then starting Sunday. I won't be able to do the steering linkage or torsion bars until they get here but I can at least get the control arms back on and the new balljoint boots on everything.
