What headers will fit???

Aluminum and electric fan system.....he had to custom modify radiator support to make this work....installer is a father son shop that's pretty reputable....they have a 2 Bay garage and only do muscle car builds and restorations...I mentioned this to him before we finished with headers and he insisting it is not a big deal and will only effect the header install....and he says if anything it should better for handling for moving the center of engine weight towards the rear of engine bay for better overall vehicle balance
