How much to cut out for fenderwell headers?

[JuanGTX]

Sorry to bring this thread up again...
I'm triying to do the same thing. I've noticed that none of the pictures above show a car with Brake Booster.... what if I want to keep it??
Would the headers fit anyway? If they fit, will heat will boil the brake fluid?
Thanks!!!

You won,t beable to use a booster,just manual disc master.I bolted mine to the top to bolts and use the Dot 5 brake fluid,it,s good to 520 degrees.Here,s a pic of my master cyl.
