I have a 302 h.o. with 5 speed out of a '88 mustang stuck in a '81 fairmont. It is stock except for aluminum intake and holley 4 brl. Factory headers with duals, no cats. Electric fuel pump. trying to build a cheap street sleeper. Looking for relatively inexpensive head options to bolt on. Any suggestions? Also, will a 75 shot NOS kit kill it? I have never had, or even been around a Ford before so need a little direction. Thanks.
