1972 chevy truck k20 brakes and exhaust.?

i have a 1972 chevy truck k20. with power disc/drum brakes. disc front drum back. someone cut my rear brake lines and put water in my brake resevoir. now theres air in all my lines and stuff. how can i get all the air out. i plugged the back brake line and am now bleeding them from the rear. is there any possibilty to getting all the air out or what. how can i go about doing this the best way. and also is it true what i hear about a sbc engine needing backpressure. then how can hot rods and or rat rods run straight headers. is there anything i can do to my carburetor to gain more hp when i run straight header. like change the jetting or something. please all your information is greatly appreciated and needed. engine is a 02 chevy crate engine with a cam and edelbrock 650 cfm carb and edelbrock performer intake manifold. hei ignition by ac delco. and champion spark plugs. and serpentine belt kit. 4 core radiator. o and the truck has no fan and runs 160 degrees all the time.1972 chevy truck k20 brakes and exhaust.?I hate to say this but you should have it towed somewhere with a pressure bleeder. I say this for 2 reasons. Reason 1 these are your brakes were talking about its the only way to stop your truck so I believe that since you have never done it before you should have a professional do it. And reason 2 every good tech knows that brake fluid absorbs water so if someone put it in your brake system then that's why you should get it pressure bled so they can flush out all the water. Make sure you tell them that there is water in the system and that it needs flushed extra good. This may not be what you wanna hear but its a professionals opinion.
