Default headers

I have a new set of header that I have had for a while. THe car is a 72 with AC and PS. It has been so long that I have had forgot what kind of brackets I need to install these with AC. The stock manifolds are on now with the compress mounted. Can someone jog my memory? I bought this car in the 70s sold it and bought it back in the late80s. Tried to put it back as it was but it really does not run that well--fast. My kids V-6 accord smokes it. Looking at upgrades to make it run better. Planning to put a 383 or larger stroker motor with other stuff at a later date. But for now I plan on going the intake carb and header deal and maybe a converter. Car is stock 350 with comp 268 cam. Will a performer intake with Holley fit under standard hood? If not I have the other hood as well.

perhaps a street rod magazine can help you figure that out ( ac brackets) they are filled with vendors selling accesories. looks like this is step in the right direction.

I'm going through the header installation right now in my 70' so I have lots of info and pictures.

I still don't have the AC side figured out yet....

From my memory there seems to be a mount for AC on these cars that you need for headers. The orginal manifolds has a mount tht serves as the lower compress mount. I just cannot remember on where to get one. Now, I remember something about cutting a stock mount but just do not remember. Any help would be appreciated
