If I put headers on my amc 360,will this affect the way it will run?I am going to remove the air pump,cruise control,and the ac compressor.I am going to keep the stock carb .I currently have the engine on an engine stand and I was going to remove the stock exhaust manifolds because it looks like the prices on a cj v8 single exhaust from the manifolds back is not much cheaper than ordering headers and mufflers.I always wanted headers and duals on my cj but i dont want to damage the engine either.If i get the headers do you guys recomend inside frame or outside frame style for my 79 cj.I have'nt even tested this motor yet this is my junkyard special so far the plugs are all equally just carboned up.No heavy oil leakage on the engine.It had oil in it.I am going to remove the oil pan have it sanblasted then paint it.I just figure I better have an exhaust when I try starting it and while its running so my neighbors dont get po'd. thanks in advance for any info.
