I'm still in Jamaica for a few more days, and I'm sure my wife isn't happy that I'm on the forum, but c'est la vie.
The only Calgary-local hemi tuner that's half-way decent is the guys at Davenport but be prepared to fork over a second-born. The best guy we've found in Alberta is out of Stoney Plain at CCMR mobile dyno. Several guys from the ALX use him and he brings his dyno down south a few times a year or he has it setup in his shop with reasonable rates.
Heather, with the long tube headers, if you're not willing to drop $1700 on the ARH/Stainless Works then look at just the OBX headers and get them ceramic coated to reduce the under hood temps. IF you're looking for a bit more economy then the JBA shorties are a good price, but you'd have better value out of a set of used GCSRT8 headers, but I believe you need a custom midpipe, cats are optional then. IF you don't ever want to touch your headers again, regardless of type, then use the Mopar headers gasket and a set of Stage 8 locking header bolts, you'll never touch them again as they can't loosen up. Torque them, heat cycle the headers a few time, retorque and install the locking wings, done.
