i cant deal with the headers anymore.. i need schumachers!

First I will say the larger header will flow a lot better. My car would probably be quicker with that type of header. I am using Edlebrock heads. My best times with 2 1/2" pipes, mufflers on is 12.00@113MPH. The only reasons I will not get bigger headers spark plug removal, looks of the engine bay and if my engine goes again. I can change engines quicker and easier for myself. I know some people will disagree.
