1978 Corvette

(Lascassas, TN, USA)

I have a 1978 Corvette project, and will be changing the intake and carb. The car has Antique plates and doesn't have to go through emissions, but a lot of equipment is vacuum operated, so I wondering if anyone knows which vacuum lines are mandatory for the car to work properyly, and which ones can be excused. Also do you think headers are worth the HP increase over true duals from the manifolds without cats? There isn't a lot of room, and starter access and burnt plugs wires, but does anyone have headers that fit extremely well and have good access?
