I do pretty much have the same car. I had absoluetely no problem with my Hooker Headers' headers. But I have no cats on my Camaro. They are the 1 5/8" competition style. For me, it took 30 minutes to install. I currently have the Weiand Action Plus 8004 intake manifold. I plan on going with the Edelbrock Performer RPM later on. The Edelbrock performer and the weiand action plus would work great with your Q-jet since they accecpt the spread bore design of the Q-jet. I personally like the holley 4150 carburetor with its plentiful aftermarket you can't go wrong. The Q-jet is a good carb though and can be a good performer. These upgrades will allow your engine to wind a little better, breathe better, and sound a thousand times better. Mufflers are up to you. I personally like the Hooker Headers' Aero Chamber Mufflers. Flows are good too just a little more expensive.
