GM HEI conversion questions

its some sort of lean burn....ive been on all the diplomat forums i could and no once could help so i stumbled on this forum and seen all the threads about the switch and figured yall would know the best even though i have a diplomat not an A body. Just so if this help its an 87 diplomat with a 318 2bbl electronic feedback carb. but now my question still remains can i use my stock dizzy without destroying anything?
