your opinions on spitfire headers

We invented some new curse words when installing my Spitfires. Actually, the drivers side went on easier than the passenger side did. The passenger side bolt holes didn't line up.
The dumps pointed right at the torsion bars, and initially, my friend put together a dual exhaust system for the headers, but I had to go get that fixed somewhere else. I ended up with no flanges to disconnect. The headers are welded directly to the exhaust pipes because of the lack of room, and the way the dumps ended up.
If I had to do it all over again, I'd just take the heads and the factory manifolds and have them professionally port matched, polished, coated, or whatever.
If I ever have to pull the engine, I'll have to cut the pipes, and then I probably WON'T put the headers back on.
The basic problem is if you have a 66 or earlier A body there just ain't no damned room for headers. Don't blame the headers. . . for all of the problems.
I might reconsider and go for a set of TTI's when my rich Uncle gets out of the poorhouse.
I don't know anything about the performance increase because I did an engine swap and the Spitfires all at the same time. GOOD LUCK!

Don't remember who said it, but: "If Mopars were easy, everybody would have one."
