there is a set of original unused maxwedge exhausts on e-bay for about 
$1000. they look beautiful. I had the same problem on my 440 with a set of 
old 60's headers because of the flange. it was a 3 part flange and had 
sealing problems from day one. the stripped out bolts on the head didn't 
help either. the pair i had was a little bent from laying around unused for 
30+ years, in my buddys garage/storage, they fit great even with power 
steering but wouldn't seal. I opted for a set of doug thorley headers (about 
$120) off e-bay brand new, and now am only blowing gaskets at the collector. 
Ha HA HA. I think copper crush gaskets are the way to go down there. the one 
part flange really made the differance, and i've noticed that the 
bigger(thicker) the better on the flanges. I had one problem on both sets, 
the place for the header bolt/stud behind the #2 opening is real tight and 
had to be installed while putting the header on. the stock manifolds seal 
real good they are easy to get to plugs, and only need one or 2 of the 
special long exhaust sleeve bolts, but don't flow the same. you'd be better 
off using a set of the swept back HP manifolds for flow, but any set of 
stock manifolds will controle heat and noise better that a cheep set of 
headers. Ceramic coating IS worth the cost.

Sorry for the long post.
