Exhaust leak!!

Exhaust leak!!
I am having one of those small problems that should be eaisy to fix, but it isn't.
I put headers on my 71' f-100 w/ 360 4speed 2 weeks ago and I just got the rest of the system on too and there is a leak on the drivers side right at the ports.
I know this should be a simple fix but I tried tightening them, loosening and then tightening, then I just put a whole new gasket on......... and it still leaks!!
I have payed close attention the the tightening patterns, What should I do?

Withe headers you need to use a header gasket from a speed shop. Those gaskets that come in the engine gasket sets will burn out in no time with headers.
I know some of the bolts are hard to get a grip on with a standard wrench when they start to get tight. I have a set of angle head wrenches from Mack that are 60 degrees on one end and 15 degrees on the other. There are a few bolts on each side that I have to use one of these on to get them tight.

thanks for responding
I am not having problems tightening the bolts, that is fairly easy, I also thought that the gaskets that came with the headers were bad so i replaced them and they still leak. I know it is the front cylinder on the drivers side because i popped the plug off while running and it stopped, then I put it back on and it started leaking again.
Is there someplace that I can take it?

When you replaced the gasket did you look carefully at the sealing flange on the header? It's possible that it got through quality control with a defect like a blob of weld or something on the sealing surface that just needs to be ground or filed flat.
You might want to consider the embossed copper header gaskets as well:

you can also use RTV they have some broze stuff that is good for something like 1300 degrees. i went through the same thing you are and i took them off put some rtv on the gasget and put it back on and i also put some rtv where the header bolts the the rest of the system and it solved my problem.

Have to checked the heads matting surface to see if the head was burned out and damage from a leaking manifold. This is a very common with fe motors. The only real fix it have the head manifold side shaved. I been running a set of Sanderson shorty now for the pass 3 yrs, there designed to just use high temp RTV (no gaskets) If your headers have only 1/4" header plate design they don't last to long until they warp. When using rtv wire brush clean the surface with a good cleaner like acetone first...my 2cents
