headswaped car with problems, i have a bad miss what could it be. LONG! please help

first of all if you have a timing adjuster you must set it back to factory timing and replace the plugs you have with a colder model i use autolight 103`s don`t use platinum models .this is what i use on my head swaped 98 ,also it is mandatory that you run nothing lower than 91 octane fuel or you will kill your engine also try to get the heat in the engine down by replacing the coolant with more water and aftermarket stuff like water wetter. and a coller thermostat 180 should do. this should fix all your problems.
