Exhausted with Header Leaks

Guys,

Just spent 6 hours replacing my header gasket on my driver's side, cranked the motor, STILL THERE.

Doug's D453 Headers
Doug's Header Gaskets
Permatex "Right Stuff" around all exhaust ports and at header flanges

Leak at cylinders 3 & 5

I torqued the header bolts starting from cylinders 3 & 5, then moved outward to 1 & 7.

What do you guys use? Any tricks or tips you guys can share? Very tempted to actually take it to the local Mopar shop to do it because I'm pretty deflated after today. It would be the first time I take it somewhere besides my garage.

Thanks in advance for any help and input.
